...but Dave Chapelle doesn't exist cause he's George "Noodles" Stone.
Marlon Williams, the real-life singer who played himself as the replacement singer at the Grammys, exists...
But Shangela, iconic drag queen, doesn't exist, cause she's just a random MC at a drag bar.
Brandi Carlile exists, we saw her duet with the Marlon guy at the Grammys...

Greg Grunberg plays Jackson's driver Phil...
...which means Greg Grunberg doesn't exist, and if Greg Grunberg doesn't exist then Heroes can't exist and if Heroes doesn't exist, does Hayden Panettierre even exist!?!?!
Charlie the dog exists.
But the real-life Charlie dog doesn't exist because Bradley Cooper doesn't exist, and since Charlie is Bradley's real dog, then Charlie can't exist therefore he's not REAL. BOO!!!!
Oh well, still obsessed with whatever world this movie takes place in.
