Like the object of the title, the raunchy romantic comedy “Sex Tape” starts off with a strong idea but doesn’t go as well as everyone involved hoped.
Radio programmer Jay (Jason Segel) and mommy-blogger Annie (Cameron Diaz) are finding it difficult, 10 years and two kids into marriage, to find the sexual spark they used to have. Annie has the notion that the couple should make a home porno — trying every position in Alex Comfort’s “The Joy of Sex” in an epic three-hour session.
No problem, until the next day when Jay realizes the video has been copied to iPads he gave to all their friends. Thus begins a frantic odyssey in which Jay and Annie try to retrieve the iPads and erase the video from each.
Alas, the script — by Kate Angelo (“The Back-Up Plan”) and thoroughly rewritten by Segel and his writing partner Nicholas Stoller (“The Five-Year Engagement”) — doesn’t generate all the laughs a premise like this could deliver, and it comes to a dead stop when Jay and Annie visit the super-positive CEO (Rob Lowe) of the squeaky-clean company bidding to buy Annie’s blog.
Director Jake Kasdan gets good comic chemistry out of Diaz and Segal, with whom he worked on “Bad Teacher,” but only sporadically finds ways for them to shine.
Opens today at theaters everywhere; rated R for strong sexual content, nudity, language and some drug use; 94 minutes.
