It looks like Seth Rogen’s directorial debut just got a little bit bigger.  The apocalypse-set comedy has recruited a few more celebrities to add to its already full cast as Jason Segel and Emma Watson will reportedly play themselves in End of the World.  The two actors will have relatively small appearances when compared to the core ensemble which includes Jay Baruchel, James Franco, Jonah Hill, Danny McBride, and Craig Robinson.

The fact that this movie has cameos in it should not be too surprising given that Rogen has gone on the record saying that the movie would be flooded with them.  Of course, none are expected to be as great as the recent Johnny Depp cameo in Jonah Hill’s 21 Jump Street; however, the Harry Potter references for Emma Watson could be a recipe for comedy gold should they go the obvious route.

Both actors are coming off of tame box office performances.  Jason Segel recently starred in The Five-Year Engagement alongside Emily Blunt in what turned out to be a Judd Apatow-produced dud.  Emma Watson on the other hand had a supporting role in the well-received indie drama My Week with Marilyn which only banked $15 million at the domestic box office.  Cameos are natural career boosters and that is why we think the appearances might help either actor’s career in the long run even if it does come in the form of making fun of their past work.
