imagine if they cast james corden as the lead actor in this film. you would have 2 james cordens on-screen at the same time, with the possibility of infinite clone replication of james corden.
now imagine that was possible in real life. carpool karaoke, but instead of a car, it's a coach full of james cordens singing along with special guest iggy azalea. 20+ james cordens badly performing shit rap music...
makes you shudder just thinking about it
