Nope. And technically in Soul Man it was the character attempting to impersonate another race, not the actor.

C Thomas Howell and Elizabeth Taylor were in the film "Il giovane Toscanini"

Wow! Very nicely done (and a valid connection, so I'll call it a win)...although the connection I'd had in mind was that the male & female leads in both films ended up getting married. Your go!

And here. We. Go.

The Accidental Tourist and Mystic River

The stories of both films are propelled by the main characters losing a child to violence?

Fraid not. Although it's a good guess.

Is it that they both received Sammy Awards?

Accidental Tourist got it for Best Score. Mystic River got it for Worst Score.

Uh.... no.

They both have a dead kid in em?

It's something about the awards won for the movies
