Same role, different movies
There are some prolific actors who play the same character in every movie they’re featured in. Vin Diesel is always the bald bad ass who likes to go fast, Danny Trejo is a mean SOB who doesn’t take nonsense from no one, and Michael Cera will forever be known as an awkward teen.
As for Eli Roth, the actor who played Donny Donowitz in Inglourious Basterds, he took up another role that was almost identical to The Bear Jew. Well, that’s a stretch. The only similarities the two characters had were that their names sounded similar (Donny and Dov), and that they were both Jewish.
