Sometimes, but not often, they nail the casting of the younger version of an actor for flashbacks, prologues, or weird side by side time travel stuff.
JGL as a young Bruce Willis in Looper? Jennifer Connelly as a young Elizabeth McGoven in Once Upon A Time in America? The entire child cast of Now and Then, which somehow all got famous?
Who have you seen that made you honestly and truly believe they could be the younger version of an actor?
