The Scottish actor's Rome was a big hit in 2005 and 2006, but was cancelled in 2008.
Now, creator Bruno Heller has completed a script for a feature-length version of the controversial drama, which also featured Ray Stevenson, Polly Walker, Kerry Condon and James Purefoy.
And McKidd is keen to revive his violent soldier character Lucius Vorenus in the film, which is reportedly set years after the series ended.
The actor says, "It (show) was very popular when it was on TV and seems like it's become more popular since it's been taken off the air... I think it'll be a lot of fun to revisit those characters."
