According to his IMDb page, Freddy Carter's first-ever film credit is 2017's Gal Gadot-led "Wonder Woman," in which he portrayed a soldier. Set during World War I, the film has no shortage of soldiers, and some outlets such as PopBuzz have said they have not been able to individually spot him among the hordes of soldiers. Still, it's experience under Carter's belt and a cool story to tell — even if viewers can't properly see him.
"Wonder Woman" is not Carter's only time appearing in the DC Extended Universe, however. According to his IMDb page, Carter had a recurring role as Jason Ripper in the television series "Pennyworth" in 2019. This series follows Alfred Pennyworth, Bruce Wayne/Batman's butler, in an alternate universe.
Being in two projects connected to Batman — with Wonder Woman being a close friend to the vigilante — could only mean that Carter was destined for his own big roles. Now, in 2021, you can catch him as a leading actor in Netflix's "Shadow and Bone."
