Film 951: This Is The End

Trivia: Rihanna actually slapped Michael Cera's face harder by each take because she was getting tired of him grabbing her buttocks.

Seth Rogen gave an interview where he described how the script by himself and Evan Goldberg combined real characteristics of the actors who then produced bizarre alt-version of themselves with elements that had absolutely nothing in common with the cast. Rogen cited Michael Cera's portrayal in the film - a drug-using, ass-grabbing, utterly obnoxious loudmouth - as funny because that character has nothing at all in common with how Cera behaves in real life.

Seth Rogen stated in an interview that at one point during production every main cast member took him aside and told him that they couldn't do what he was asking him to because it was going too far and getting too extreme. James Franco was the only cast member that never turned anything down.

Initially Michael Cera wasn't really slapping Rihanna's butt, but rather making the motion and stopping right before touching her. As a result, the scene wasn't working on camera because it looked too fake. Eventually Cera asked Rihanna if he could really slap her butt, she said yes but on the condition that she be allowed to really smack him across the face each time. Cera agreed.

Most of the paintings that can be seen hanging in the background were actually painted by James Franco.

Directors Evan Goldberg and Seth Rogen reportedly approached Cameron Diaz, Edward Norton, Mila Kunis and Elizabeth Banks to make cameos as themselves at James Franco's party. They had to turn down the offers due to scheduling conflicts on other films.

In an interview with the Rod Ryan Show on Houston radio station 94.5 The Buzz, Craig Robinson revealed that Jonah Hill improvised asking for a bite of the Milky Way. The other actors improvised the following conversation regarding who gets to eat the Milky Way.

According to Seth Rogen about 50% of the movie was ad libbed.

According to Seth Rogen, Danny McBride was the person who made everyone laugh and break character the most. At one point, it took 18 takes and over an hour for the cast to get a joke on film because Mcbride's delivery kept making everyone laugh.

An early idea for the story had the film taking place at a studio where a Busta Rhymes music video shoot was taking place with the main characters present when the apocalypse begins.

According to Seth Rogen there is a secret celebrity cameo in the movie that only lasts "a split second" that no one has been able to spot yet.
