23. Colin Hanks
Famous Family: Actor Tom Hanks (father); actress Rita Wilson (step-mother)
He can be funny (see Orange County), sad (see Mad Men), and downright scary (see Dexter). Much like his dad, it's hard to not like Colin Hanks. And it's hard not to draw comparisons when it comes to their looks, mannerisms, and acting style.
While father and son have been known to work together on occasion (Colin appeared in the HBO mini-series Band of Brothers, which Tom produced), Hanks the younger has really seemed to blaze his own career path, easily alternating between television and film with equal aplomb and affability.
