'This Is' The Summer's Funniest Movie

On paper, This is The End -- an apocalyptic comedy starring James Franco, Seth Rogen, Emma Watson, Rihanna, Michael Cera and Craig Robinson as "themselves" -- should be the best time you'll have at the movies this summer. In reality, it is.

From the minute this insane adventure starts -- when a party at James Franco's house is interrupted by The Rapture -- the cast will have you rolling on the butter-soaked floor as each revels in sending up their celeb persona, and gleefully takes potshots at their friends' as well.

The film is simultaneously a bromantic comedy, a poignant morality tale, a balls-out brilliant comedy, a special effects extravaganza and easily the funniest 106 minutes you'll spend in a theater this summer. Watch a clip!

The cast also filmed this Real World spoof that you must see to believe!

This Is The End opens Friday.
