Actor Michael Douglas says he initially had doubts about having young actor Shia LaBeouf in the sequel to Wall Street.Douglas, who reprises his Oscar-winning role of Gordon Gekko in the new film, said, “Shia, honestly, we were all not sure about whether he had the chops. As you remember from the first, Charlie Sheen (as Bud Fox) carried the movie.”But he said the 23-year-old nailed it. “He knocked it out of the park. I’m so proud of him,” he said.
