According to the Russo brothers, the Old Man Cap look was achieved largely through makeup. "We did a lot of practical effects, so it was a very elaborate makeup job that was then augmented with CG, because theres certain things that you cant do with makeup in order to make Cap credibly that age," said Anthony Russo.
