In retrospect, Forgetting Sarah Marshall shares many elements in common with another 2008 movie: Iron Man. Both were launching pads for a plethora of separate, but ultimately inter-related films.
Forgetting Sarah Marshall starred Jason Segel as a musician who yearns to write a puppet Dracula musical. Via IMBd:
Screenwriter and star Jason Segel told New York Times interviewer Dave Itzkoff that both the naked breakup and Dracula puppet musical scenes were drawn from his real life experiences. In the article, Segel admitted that he really did once have a girlfriend who broke up with him while he was completely naked (although rather than being devastated during it, he thought to himself, "This is hilarious. I cannot wait for her to leave so I can write this down.") And before he was a successful actor, Segel tried to write a musical adaptation of "Dracula" for puppets.Now having had a successful starring role along these very realistic lines with Forgetting Sarah Marshall Segel is now co-starring in the new Muppets movie, for which he also co-wrote the script. (He sadly sings the Muppet Show theme song on the piano before dissolving into tears at his lowest point in Forgetting Sarah Marshall.) Russell Brand, who stars here as spacey British pop star Aldos Snow, later reprises his role in 2010 in the spin-off sequel Get Him To The Greek. Not only that, but Jonah Hill stars in both films as different characters, but each of whom worship Snow and put up with abuse to be around him.
Iron Man, on the other hand, stars Robert Downey Jr. as Tony Stark a.k.a the titular character. Since the massive success of the first movie, a sequel was made in 2010 and Iron Man 3 is planned for 2013. Before that happens, though Joss Whedon-penned The Avengers Film is set to tie the whole room together. Via Wikipedia:
It is part of the Marvel Cinematic Universe, which crosses over several Marvel superhero films including Iron Man (2008), The Incredible Hulk (2008), Iron Man 2 (2010), Thor (2011) and Captain America: The First Avenger (2011).Iron Man came out in May and The Incredible Hulk came out in June so it's still technically first. Plus, Iron Man made twice as much money, so it's success was the real reason for this franchise's existence. Just like Forgetting Sarah Marshall!
I just wanted to get that off my chest. I guess I forgot to review the movie. Here it is:
It's great. Go see it if you haven't already. The extended version is even funnier.
