Sometimes celebrities turn down projects that turn out to be massive hits. Ouch.

Some examples:

Molly Ringwald - passed on Pretty Woman.

Mel Gibson - passed on Gladiator.

Will Smith - passed on The Matrix.

John Travolta - passed on Forrest Gump.

Michelle Pfeiffer - passed on The Silence of the Lambs.

What singers passed on hit songs? I only know Britney Spears passing on Umbrella.

Britney passed on telephone too.
Kylie passed on Toxic.

Oh and Travolta on Chicago

Kylie Minogue passed on Toxic.

This more of a "she didn't get the song" type of thing, but whatever. Britney didn't get Get Outta My Way (I think she was supposed to anyways )

Britney - Umbrella
Mary J. - Umbrella

Break your heart by Taio Cruz was offered to Cheryl Cole

Sophie Ellis-Bextor turned down Can't Get You Out Of My Head.

Pink passed on Since U Been Gone, if I'm not mistaken?

Sandra Bullock turned down the Hilary Swank role in Million Dollor Baby. Swank went on to win a Oscar for the role.

Sandra end up winning an Oscar though, a couple years later.

TLC was offered Baby One More Time.

Gwyneth Paltrow was James Cameron's 1st choice for the role of Rose in Titanic.

*Beyonce Telephone oops gif*

Christina Aguilera passed on Miss Independent

Mary J. Blige passed on Umbrella

Janet - How Will I Know
Janet - I'm a Slave 4 U
Christina Millan - SOS
Britney - Milkshake

Oh God... I'm glad they did it... it wouldn't fit them...

I heard Janet turned down I'ma Slave 4 U.

Julia Roberts passed on both The Blind Side and The Proposal, the 2 highest-grossing movies of Sandra Bullock's career
