One of the odder things about the show is that it consists not just of regular episodes and seasons, but also TV movies, online webisodes and spin-offs. The mass of material, and the lack of one easily-available "complete franchise" box set and variable streaming availability has made following the series and watching it more complicated than it really should be. This guide should - hopefully - make the situation clearer:
The show's production order is probably the best viewing order as well, since this is the order the series originally aired in and is what most people viewed the series in. This also best protects later spoilers and crucial plot revelations.
The Mini-Series (2003)
When BSG was rebooted in 2003, it first returned as a pilot mini-series consisting of two 90-minute episodes. This was initially released by itself on DVD. Later on, it was incorporated into the US Season 1 DVD box set but not in the UK Season 1 DVD box set. For UK DVD watchers, the mini-series still has to be purchased separately. The mini-series is included in the Complete Series Blu-Ray set.

Webisodes: The Resistance (2006)
Between Seasons 2 and 3, NBC requested that the BSG team produce ten short "webisodes" to advertise the return of the show. The producers agreed and filmed ten short segments which, when combined, form a 24-minute "prelude" to the third season. However, a legal dispute over pay for the webisodes (which also affected studio-mate series The Office) caused delays in production. As a result, The Resistance was issued only in standard definition (even on the Blu-Ray release) and with a minimum of post-production. However, they do set up the state of play at the start of the third season. They can be found on the American Season 3 DVD release, but not on the UK DVD release. They are included in the Complete Series Blu-Ray set in all territories, however (under the special features for Disc 2 of Season 3).

TV Movie: Razor (2007)
Produced as a straight-to-DVD special between the third and fourth seasons, Razor was a 90-minute TV movie set towards the end of the second season and expanded on the backstory of the battlestar Pegasus. A series of webisodes set during the First Cylon War preceded Razor, but these have been integrated into the episode itself on the home media releases.
Season 4, Part 1 (2008)
- 401: He That Believeth in Me
- 402: Six of One
- 403: The Ties That Bind
- 404: Escape Velocity
- 405: The Road Less Travelled
- 406: Faith
- 407: Guess What's Coming to Dinner?
- 408: Sine Qua Non
- 409: The Hub
- 410: Revelations
The fourth season of Battlestar Galactica was announced as being the last. However, SyFy delayed transmission of the season by several months due to problems caused by the 2007-08 Writer's Guild of America Strike. They then split the final season in half, airing the two halves a year apart. Although this gave more time for post-production, it caused great irritation in the fanbase.
Webisodes: The Face of the Enemy (2008-09)
These webisodes were produced between the two halves of Season 4. However, due to some slight confusion, they are set between Sometimes a Great Notion and A Disquiet Follows My Soul rather that directly between the two halves of the season. This is because Season 4, Part 2 was originally supposed to end with Sometimes rather than Revelations, but it was decided that Revelations made for a more shocking cliffhanger. Fortunately, the webisodes do not contain any major spoilers for Sometimes. They are not included on either the US or UK DVD sets, but can be found on the Complete Series Blu-Ray set.
Season 4, Part 2 (2009)
- 411: Sometimes a Great Notion
- 412: A Disquiet Follows My Soul
- 413: The Oath
- 414: Blood on the Scales
- 415: No Exit
- 416: Deadlock
- 417: Someone to Watch Over Me
- 418: Islanded in a Stream of Stars
- 419: Daybreak, Part I
- 420: Daybreak, Part II
- 421: Daybreak, Part III
TV Movie: The Plan (2010)
The Plan was produced as an attempt to address fan concerns that the Cylons had never actually had "a plan" (as described in the opening to every episode of the first three seasons), and effectively presented everything that happened in the first two seasons from the Cylon POV. However, fan response to the TV movie was muted, especially coming after the conclusion of the series as a whole. The Plan is not part of the Complete Series Blu-Ray set and has to be purchased separately.
Season 1 (2010)
- 101: Pilot, Part I
- 102: Pilot, Part II
- 103: Rebirth
- 104: Reins of a Waterfall

- 119: Apotheosis
Caprica is readily available on DVD, but has not been released properly on Blu-Ray in the UK or USA. Oddly, complete series box sets on Blu-Ray are available from France, Germany and Sweden.
Blood and Chrome (2012)
Blood and Chrome was a proposed second prequel series, taking place sixteen years after the events of Caprica and forty-two before the events of the mini-series. The planned series would have covered the final two years of the First Cylon War. However, the series was never made leaving the pilot as a stand-alone TV movie.
Watching BSG in chronological order will likely be fairly confusing. BSG is reliant on backstory revelations delivered at key points in the narrative and watching later series and TV movies can result in significant spoilers. Therefore, this is only really recommended as a rewatch experiment.
This is the (rough) show timeline, sans spoilers.
c. 4000 BF (Before the Fall): The Thirteenth Tribe leaves Kobol to colonise Earth. The semi-canon comic book BSG: The Final Five begins.
c. 3600 BF: The Book of Pythia is written.
2000 BF (1,942 years before the events of Caprica): The remaining Twelve Tribes depart Kobol to colonise the Twelve Colonies.
58 BF: Caprica takes place. The epilogue to Season 1 takes place several years later.
52 BF: The First Cylon War begins.
51 BF: The semi-canon video game Battlestar Galactica: Deadlock takes place.
42 BF: Blood & Chrome takes place.
40 BF: The First Cylon War ends. The flashbacks in BSG: Razor take place.
30-20 BF: The flashbacks in BSG: Occupation (episode 201) take place. The semi-canon comic book BSG: The Final Five ends.
c. 6 BF: The flashbacks in BSG: Hero (episode 308) take place. Dialogue in this episode suggest it is more like 1-2 BF, but this was a continuity error.
0: The Fall of the Twelve Colonies. BSG: The Plan begins. BSG: The Mini-Series takes place.
0-1 AF (After the Fall): BSG: Seasons 1-2 and the remainder of The Plan and Razor take place.
2-4 AF: BSG: Seasons 3-4 take place.
The chronological viewing order of the franchise is therefore as follows. I do not recommend you watch the show in this order for a first watch:
- Blood & Chrome
- BSG: The Mini-Series
- BSG: Seasons 1-2
- BSG: Razor takes place between Season 2, Episodes 17 and 18.
- BSG: The Plan takes place betwen the mini-series and Season 2, Episode 20.
- BSG: The Resistance webisodes
- BSG: Seasons 3-4 (Part 1)
- BSG: The Face of the Enemy webisodes
- BSG: Season 4 (Part 2)
In 2017 the video game Battlestar Galactica: Deadlock was released. This was an approved product worked on by some of the team at SyFy who worked on the show, although Ronald D. Moore was not involved. The video game tells the story of the first year or so of the First Cylon War.
