The tireless James Franco, who has both "Oz the Great and Powerful" and "Spring Breakers" in theaters right now, stopped by the "Late Show with David Letterman" last night to promote the latter film and quiz his host about why its director, Harmony Korine, had reportedly been banned from the show.

According to "legend," as recounted by the actor, Korine had three appearance on Letterman, first to promote "Kids," then for "Gummo," and finally for his book "A Crackup at the Race Riots." A fourth booking was scheduled but never happened, and Franco asks Letterman why, saying that he'd heard his friend had gotten tossed for pushing fellow guest Meryl Streep backstage, with Franco admitting that Korine was often out of it in that era.

"I went upstairs to greet Meryl Streep and welcome her to the show," said Letterman, who mimed knocking on the door. "And I looked around, and she was not in there, and I found your friend going through her purse," he said. "True story. And so I said, 'That's it, put her things back in her bag and then get out of here.'" With Franco vouching for the now stable filmmaker, Letterman did say he'd have him back.
