The attempt of two lazy guys to stay ahead of a band of vicious killers after one of them witnesses a murder is the plot of the newly released “Pineapple Express”, starring Seth Rogen and James Franco.

The two broke into showbiz together starring in Judd Apatow’s 1999 television series, "Freaks and Geeks." Franco’s movie career continued its explosion with roles in Sam Raimi’s "Spider-Man" and its sequels. Along with the release of the comedy, the actor was also celebrating having just graduated from university.

Rogen on the other hand also starred in Apatow’s "The 40-Year-Old Virgin”, followed by "Knocked Up" and "Superbad." Franco also has just finished portraying Scott Smith opposite Sean Penn in Gus Van Sant's upcoming “Milk.”

The script for “Pineapple Express” was written by “Superbad” writers Seth Rogen and Evan Goldberg. The movie promises to combine comedy with action and with a huge amount of weed smoked by the protagonists. Thus it promises to make its viewers have a good time. “A weed action movie” – they called it.

Hitting theatres next Friday, the comedy tells the story of Dale (Rogen), who gets into weed-enhanced panic after witnessing a murder. Dale seeks help with his dope dealer Saul (James Franco), but the strange duo is soon being chased by crooked cops, some other trusted followers and another dealer (Danny McBride). Singer Huey Lewis wrote the film's theme song.

At the Los Angeles premiere, stars such as Jim Carrey, Daniel Craig, Emile Hirsch, rapper Kanye West, Alicia Silverstone, Jane Lynch, Christopher Mintz-Plasse, Amanda Peet, Jason Schwartzman and Jack Black are among the ones who gathered on the red carpet to celebrate.
