Sad to reveal: It's a Prequel, therefore no Kate Beckinsale or Scott Speedman... BOO.
Collider chatted with producer Tom Rosenberg and received some updates on Underworld 3: The Rise of the Lycans (and a possible 4th film), Crank 2 and Game. Here's a clip on the "Underworld" franchise: It's a theatrical release definitely. I feel great about that. I think it's the strongest story that we've put together of the three. I think it's really terrific. I think it leads to a 4th. When we did the 1st Underworld, we imagined three--the 1st one, a sequel and then a prequel. The 3rd is a prequel, so the 4th would carry on where Kate and Scott Speedman left off after 2, so I think this is going to be terrific really this one.
