LOS ANGELES (AP) -- If there's going to be a third "Transformers" movie, director Michael Bay says he'll be back to make it.
And star Shia (SHY'-uh) LaBeouf (luh-BUFF') promises it'll be darker than the first two.
Bay and LaBeouf talked about the prospects of another sequel Monday night at the Los Angeles premiere of the second installment, "Transformers: Revenge of the Fallen."
While a third chapter hasn't been officially announced, Bay says he intends to return to the franchise if No. 3 moves forward. But he says he needs some rest first, having just finished the second one.
LaBeouf says a third movie might move beyond Earth and be "more of an intergalactic thing." And hinting at a darker tone, he says, "Someone has to die."
