The Taking of Pelham 123, Denzel Washington & John Travolta?

Okay so I just watched The Taking of Pelham 123 on encore. And Denzel Washington and John Travolta weren't even in it. I checked the info on the guide and it said they were in it and I remember when it first came out they were in it, so does anyone know why they werent in it??
Update: Oh and there names weren't in the credits, but everywhere else. And DWs character was a white guy and JTs was a younger guy with black hair
Update 2: And I checked the date, it said 2009, but it did look kinda old
