FX has said “I do” to “The Proposal,” securing the TV rights to this weekend’s box office winner.

FX has already secured the TV rights to “Transformers: Revenge of the Fallen,” which is expected to be next weekend’s box office champ.

Cabler sealed a standard four-year movie license deal with Disney for “The Proposal,” which opened with a strong $34.1 million domestic gross over the weekend.

FX will ultimately pay 12% of “The Proposal’s” final gross for the movie, which will be available to the cabler about 30 months from now — in late 2011.

As part of the deal, FX has also picked up the rights to the Miramax release “Adventureland,” which has grossed about $16 million at the box office.

It’s been a busy summer of acquisitions for FX, which has also secured the rights to previous weekend winners “Night at the Museum: Battle of the Smithsonian,” “Star Trek,” “Monsters vs. Aliens” and “X-Men Origins: Wolverine.”

One of the few summer champs FX hasn’t secured, “The Hangover,” had gone to Turner as part of a larger Warner Bros. package.

Deal with Disney reps FX’s diverse studio dealings, having recently also picked up titles from sibling 20th Century Fox (“Museum”); Paramount (“Trek” and “Transformers”) and DreamWorks Animation (“Monsters”).

As is standard, Disney will retain rights to carve out a broadcast run or two for “The Proposal” during FX’s window.
