Jennifer Lawrence could be the key to a 'Sweet Valley High' movie.

Screenwriter Diablo Cody has been attached to a potential movie for some time, but has suggested the inclusion of the Oscar-winning actress is what's needed to ensure the much-discussed film gets made.

Asked about the prospect of the movie - based on the novel series about twins Elizabeth and Jessica Wakefield - coming to fruition, Diablo said: ''You always need that wild-card element who actually gets things moving. Maybe if Jennifer Lawrence said tomorrow that she wants to play Elizabeth and Jessica, the movie gets made.''

And asked whether she was happy for her plea to be made public, the screenwriter told Vulture: ''Please. Jennifer Lawrence, you can get me an automatic green-light for Sweet Valley High. Let's do this!''

Diablo insisted that despite her best efforts, it's proven to be incredibly tough to get the movie off the ground.

She explained: ''I get asked about 'Sweet Valley High' more than anything else, and it's interesting that a project that didn't go forward would get that many questions.

''That shows there's a huge appetite out there for a 'Sweet Valley High' movie. I just can't get the f**king thing made!''
