Shia LaBeouf has confirmed one of the worst-kept secrets among '80s fans: He will indeed co-star opposite Michael Douglas in Oliver Stone's follow up to 1987's Wall Street.

LaBeouf seems to be carving out a niche in the '80s world in fact. He appeared in the 2007 film version of Transformers (and will appear later this summer in the sequel Transformers: Revenge of the Fallen) as well as playing opposite Harrison Ford in Indiana Jones and the Kingdom of the Crystal Skull. (If she shows up in the remakes of Valley Girl or Heathers, the circle is complete.)

Filming of the Wall Street sequel, which according to the AP is again called Money Never Sleeps (the title keeps changing), is set to begin in August. But first, LaBeouf tells the Associated Press that he needs a serious primer on the financial world.

"I don't know what ... a credit derivative is," LaBeouf said. "I have no idea. I don't know what a CPO is. IPB. LVC. You gotta know ticker names."

That's odd. All Charlie Sheen had to know in the original flick was how to make sushi and keep Daryl Hannah awake. How times have changed.
