Cute kid actors who grew up to be not so cute...

Jerry Mathers

Matthew Broderick

Ron Howard

Most of 'em.

Heh. When I read the title of the thread, I thought I’d respond with Jerry Mathers and Ron Howard.

Even more than Ron, his brother Clint.

Danny Bonaduce

But the OP specified, “not cute”. I’d call Clint Howard repulsive/horrid/etc.

Haley Joel Osment.

Macaulay Culkin

I guess Jackie Coogan–though Uncle Fester *was *awfully cute, in his own way.

Mason Reese

How unfortunate.

Clint was disturbing to look at as a kid too.

I don’t think Mason Reese was ever “cute,” not even as a fetus.

Mason’s mother, in her memoirs, describes the bloodcurdling screams of the ultrasound technician and obstetrician.

Oh, I don’t know. Some things are cute because they’re ugly. I don’t think the young Mason Reese was ugly, but he wasn’t as attractive as many other kids. But I do think he was ‘cute’ in his way. Definitely not-so-cute now.

I can’t hold looking bad in a police mug shot against anyone.

The Olsen Twins

Billy Mumy. Angela Cartright. Both from Lost in Space.

Again, *hideous *troll-children. Never “cute,” and grew up much prettier than anyone would have predicted.
