The Norbit star, 38, was practicing for a charity race on the Irwindale Speedway to promote his upcoming film Redline, when he lost control of the red Ferrari Enzo and ploughed it into a concrete barrier.
The film's publicist, Wendy Zocks, says, "He walked away completely unscratched, but probably a little shaken."
And while Sadek is thankful the actor survived the incident, he is devastated his "dream car" got written off in the process.
He laments, "I'm glad Eddie came out of the crash OK, but my dream car got destroyed.
"I went to my trailer for about 15 minutes and I thought, 'There's people dying every day. A lot of worse things are happening in the world.'"
Only 400 Ferrari Enzos, made between 2002 and 2004, exist in the world.
