Films Young actors who look like older actors

I've been watching a few films lately and Paul Dano seems to be popping up more and more. It seems with each passing film I see him in he's evolving into James Spader (especially a younger James Spader). I'm now just waiting for the movie that casts them together as father and son (or younger and older version of the same person like they did in Looper - but without prosthetics).

Vs And younger Spader


What other actors could you see playing the roles of younger versions/children of older actors?

 

I always thought that Jim Caviezel had something alike Charlton Heston.

 

There is also Tom Hardy who have a very similar voice to Topol ( Tyvie in a fiddler in the roof)

 

William Fichtner could so easily pass as Christopher Walken

 

Actors playing rolls younger than they are is probably more common.

However, while you wouldn't say he was young exactly, I suppose one of the classic examples of "playing younger" is the late Clive Dunn:



He was only 51 when this was recorded, and one of the younger Dad's Army cast members, despite playing one of the oldest. Arthur Lowe was 5 years older, and John Le Mesurier 8.
