https://en.wikipedia.org/wiki/Steve_Rogers_(Marvel_Cinematic_Universe) Of course a person playing an older version of a character can be done with makeup or a prosthetic or CGI. https://www.imdb.com/title/tt4154796/mediaviewer/rm3250236929 The contemporary, as is. https://www.imdb.com/title/tt4154796/mediaviewer/rm3170809857 Or young but in another time. https://www.imdb.com/title/tt0458339/mediaviewer/rm2479472384 Sometimes a little CGI here & there can go a long way.

People of various ages can be put into old and new movies in the form of a deep fake. https://screenrant.com/falcon-winter-soldier-billy-dee-williams-mark-hamill-deepfake
