"Man-boy" films

Except that in none of the romantic comedies was the leading man anywhere that young. Cary Grant was in his 50s, Rock Hudson was 33-38, and Frank Sinatra was 39-43. The typical 25-year-old would be cast as the office boy or the delivery guy.

I stand corrected, then.

Just thought of one: Brendan Fraser in Blast from the Past.
