"You'll get in the car afterward and talk about how funny the movie was," Segel told THR. "Then you'll have the real discussion about how you're not having enough sex."

Cameron Diaz and Jason Segel weren't ashamed of their Sex Tape at the film's Thursday-night premiere at L.A.'s Regency Village Theatre. Fans dressed in Sex Tape-themed tank tops, robes and sleep masks, chanting for the duo as they made their way down the red carpet.

Diaz, who arrived in a shimmering black bodysuit, found herself cast opposite Segel again after 2011's Bad Teacher. "In Bad Teacher, we only got to work with each other for a couple weeks because we only had a couple of scenes together," she told reporters on the red carpet. "In this movie, we got to partner up together, and we're nearly together in every scene, which was so much fun. He's such an amazing partner in comedy, and he's a great friend."

The comedy, which has Segel and Diaz playing a pair who hope to spice up their marriage but accidentally share their X-rated footage with their family and friends via the "cloud," reunited the two with Bad Teacher helmer Jake Kasdan, who also directed a teenage Segel in the Freaks and Geeks pilot back in 1999. "They get to know each other better, they make each other funnier and they're really generous with each other," Kasdan said of the onscreen couple.

Segel, who penned the screenplay with Kasdan over three years, was both puzzled and inspired when the virtual storage-space technology had first emerged. "It seemed like we were being asked to put our personal information into something totally unsafe, so that was where some of the ideas started," Segel told The Hollywood Reporter while lounging on a large bed at the premiere's afterparty, held at Westwood's W Hotel. "This was right at a time when no one even knew what the cloud was. And they didn't pick a good name, in my opinion! It's not called the vault. It's called the cloud — sometimes, it just rains for no reason."

The How I Met Your Mother alum also noted that, title aside, the comedy is somewhat of a quest film. "You can really watch a movie from an era and there's some classic comedies that just hold up forever," he explained. "This to me sort of harkens back to the old Adventures in Babysitting-style comedies and Romancing the Stone where it's a one-night adventure. It's wrapped in this sort of 'sex tape' element, but it's really a one-night adventure to try to reclaim something that was yours."

Segel continued, "It's a great date movie, because I think you'll get in the car afterward and talk a little bit about how funny the movie was. Then there will be an awkward silence, and then you'll look at each other and you'll have the real discussion about how you're not having enough sex together."

Also spotted at the premiere were Metta World Peace, Alan Thicke, The Game's Brittany Daniel, Breaking Bad's R.J. Mitte and New Girl's Lamorne Morris.

Sex Tape will be exposed in theaters July 18.
