Shia LaBeouf reveals Transformers 2 was mainly improvised

He tells E! Online, "We didn't have a script the second time! It was like a two-hour SNL (Saturday Night Live) skit with explosions. We were sort of riffing."

But he insists the third installment, Transformers: Dark of the Moon, which is due to hit cinemas later this month (Jun11), will be at a much higher standard, "This is really the best script we've ever received."
