Also, it looks like that RUSH casting call
was, in fact, for GTA V:
Albert De Silva - now we know he's called Michael.
Kevin De Silva - name will obviously be different, but otherwise we can probably expect the profile to match. Michael's son.
Harut Vartanyan - (different name bla bla) probably Franklin's boss.
Nervous Jerry - this is most likely Ron.
Simon - probably Trevor.
Expect to see the other listed characters show up in some shape or form, albeit with different names (although I hope "Mrs. Bell" stays Mrs. Bell, and that Phil shows up at some point as a result)
