Two issues with Stephen Saito‘s “The 10 Most Slanderous Slights” piece on ifc.com. One, it’s understandable why people might assume that Tom Cruise’s “Larry Grossman” character in Tropic Thunder is based on on Viacom chief Sumner Redstone, except he doesn’t look or sound like him. (I think Cruise is just playing a generic Hollywood bully-boy mogul.) And two, I was always told that Steve Martin‘s bearded producer character in Grand Canyon wasn’t based on action guy Joel Silver — I heard Larry Gordon.
