Actors playing younger version of another actor

Sure. As would Tina Turner’s brief appearance at the end of What’s Love Got to do With it?, after Angela Basset had done all the heavy lifting.

The OP says “more than one movie”, not “more than one franchise” or “for different characters in unrelated films”, so the X-Men references from the first reply should count.

You’re right, I should have been more descriptive in my post. My apologies. I was looking for different characters in unrelated films.

If instead of James McAvoy as Professor X, they had gone with Tom Hardy, that would have been what I was looking for, since he technically played a younger Picard in Star Trek Nemesis.

Or to stretch my premise a bit, if they used the same actor for two different remakes playing the same characters as the original actor. For instance, if they made a T.J. Hooker movie starring Chris Pine, as that would make two characters that he and William Shatner both portrayed.

I agree Baker is the only one who found an example that’s fully in keeping with the spirit of what the OP wanted. But Superdude and I were within the letter of the OP.

I agree. I really had my eye on some of the other responses.

If there was any justice in Hollywood, Leelee Sobieski would have a permanent job as a younger Helen Hunt.

Throw Jodie Foster into the mix, too.
