There was just one problem, he added: I didnt understand the script.
A few months afterStar Warsarrived, Pacinos hot streak ended with the flopBobby Deerfield.
THE VERDICT:Probably for the best.

(A more fun counterfactual: envisioning aScarface-era Pacino shooting Greedo with a laser machine gun.)
Darren Franich
What if Matthew Broderick had played Walter White in Breaking Bad?
“We were like, ‘Really?

What if Bridget Fonda had played Ally McBeal on Ally McBeal?

(Flockhart is back in prime time with CBSSupergirl.)

“It was her part.
Every actor hopes for a part that lets them shine like that.”
Dont worry, Molly, you were perfect in plenty of iconic films.

I cant follow it up with a gay-cowboy movie!
THE VERDICT:Hard to tell.
But its hard to argue with the quietly heartrending film we actually got.
Keith Staskiewicz
What if Bruce Willis had played Sam Wheat in Ghost?
He eventually did play a ghost inThe Sixth Sense,and it didnt hurt his career one bit.
Bill Keith
What if Will Smith had played Neo in The Matrix?
Keanu Reeves, of course, became the one to swallow the red pill.
