Katy Perry is willing to camp outside of a theatre to see Seth Rogen's upcoming R-rated animated film Sausage Party.

The Pineapple Express star recently released the red-band trailer for latest project, which takes place in a grocery store with raunchy talking foods. The preview has already raked in more than two million views, and the pop star is one of the many people eager to view the feature, which doesn't hit cinemas until August (16).

Katy took to Twitter on Wednesday (16Mar16) and shared the link to the movie's teaser, adding: "Omg. I will camp overnight in line like a kid at a (popular clothing store) Supreme store to see this."

Seth took note of the Roar singer's excitement and wrote back, "@katyperry I think we can proooooooobably organize a screening for you."

Hype for the film started at Austin, Texas' South By Southwest festival on Monday (14Mar16), when Seth and his producing partners screened a rough cut of the movie for the first time.

Luckily, the work-in-progress received rave reviews by viewers in the audience and critics alike, which was a relief to Seth, who told the crowd in a post-screening question and answer session that the film took eight years to make since studio bosses were nervous about producing in the project.

Seth was eager to take a chance at making an adult animated film that had never been done before and he was thrilled when top Hollywood producer Megan Ellison, who counts Zero Dark Thirty and American Hustle as some of her biggest pictures, came on board.

"We would look at what animated movies did," Seth said. "People project emotions on things around them - onto their toys, onto their cars, onto their pets. That's what Pixar has done for the last 20 years. We thought what would it be like if our food had feelings. We very quickly realised that would be f**ked up, because we eat it."

Sausage Party features voices from Seth, Salma Hayek, Edward Norton, James Franco, Kristen Wiig, Paul Rudd, and Bill Hader, among others and famed Disney composer Alan Menken is slated to create the score.
