While the Extended Version of Spartacus: Blood & Sand Season 1 seem kind of false, some of the differences in the prequel season Gods of the Arena are a real improvement, sometimes the differences just lead to another experience. And the Extended Versions really press any buttons: there are extended plot scenes, an optimized cut and new footage, especially in the sex and nudity scenes. As violent and revealing the series was, there are some scenes that make the intention to not scare the audience away. As a result of that, alterations of any kind were made.

On Blu-ray, the uncensored and uncut version has been released. For some reason, the cover of the UK Blu-ray doesn't say the UK Version contains the Extended Version as well. One won't notice until the disc is in the player.

In total, 5 of 6 episodes have been altered. Only episode 2 has remained unchanged.

The fight is longer. The opponents puts a chain around neck of Batiatus' gladiator.
8.5 sec

6:12
After he took his opponent down by sword, Gannicus is able to block the following attack (also in the TV Version) and stabs him in the back. Then he pulls out the sword. The crowd is cheering. The shot of Gannicus stabbing the sword into the same wound and pulling it out of his oppenent, who's squalling in pain, is also in the TV Version.
Interestingly enough, the high angle shot of the sword in the back is equal in both scenes. Meaning: it's been used twice in the Extended Version. But that's barely recognizable if one is watching the episode.
