Just watched it, and although...

Just watched this (a trade screener DVD from the Australian distributor) and although it has a terrible plot, very low production values and terrible acting, the following portrayals were pretty good:

Charlie Sheen - VOICE: spot on, LOOK: pretty close, MANNERISMS: spot on
Angelina Jolie - VOICE: so, so, LOOK: slight resemblance, MANNERISMS: exagerated
Robert DeNiro - VOICE: pretty close, LOOK: pretty close, MANNERISMS: pretty close
Tom Cruise - VOICE: pretty close, LOOK: very close, MANNERISMS: slighty exagerated
Usher - VOICE: haven't heard him talk so can't comment, LOOK: spot on
Kanye West - VOICE: same as Usher above, LOOK: very close
Justin Beiber - VOICE: same as the two above, LOOK: close enough (I guess)

The following were terrible portrayals (they either didn't look like who their chosen celebrity, didn't sound anything like them, or both; or the mannerisms were over exagerated):

George Clooney, Brad Pitt, Donald Trump, Paris Hilton, Justin Timberlake, Ashton Kutcher, Mark Zuckerberg, Lady Gage, Kim Kardashian etc etc

Especially the Justin Timberlake guy - did NOT look anything like him!

See it out of curiosity only. Don't expect any big laughs.

Just my thoughts.
