20th Century Fox’s Assassin’s Creed is slowly but surely starting the engines on its marketing, with many believing that a trailer for the film is right around the corner. Fans have already gotten several glimpses of the cast in action, including star Michael Fassbender.

Now, two new stills featuring Fassbender have found their way online. One shows Fassbender in the present as Death Row inmate Callum Lynch, while the other features Fassbender in action as Callum’s 15th-century ancestor Aguilar.

The images, which were posted online by the Brazilian-language entertainment website Omelete, show off both the action of the 15th century and a shot of Callum looking as though he’s had better days. The two images together further highlight the differences in Fassbender’s look between the two characters, with the characters almost looking like they’re being played by different (though similar looking) actors.

There’s only so much that we can draw from these images, of course, since both Callum and Aguilar are new characters created specifically for the film. Though they expand on the Assassin’s Creed universe, there isn’t a specific moment from the games that we can point to and say that either of these shots is a reference. When combined with some of the other Assassin’s Creed shots that have been released lately, though, we’ll at least start to get an idea of the style and feel of the film.

It will be interesting to see how well the movie balances the past and the present. Unlike movies such as Captain America: The First Avenger that featured a story mainly in one time period bookended by scenes set in the other period, Assassin’s Creed should jump back and forth between the two. The stark difference between the two settings will ensure that there isn’t any confusion about which period we’re in, but the two different settings could cause pacing problems if they aren’t handled well.

Some Assassin’s Creed fans may be put off by the fact that the movie isn’t adapting any of the games, though they can be happy to know that at least they won’t have to sit through a bad adaptation of one of the games. It remains to be seen how well the movie will fit into the larger Assassin’s Creed universe, but if it does well then we may see more familiar aspects from the games in future sequels.
