15 actors on what filming sex scenes is really like.

Salma Hayek’s breakout role was alongside Antonio Banderas in the 1995 thriller Desperado, and it featured a sex scene she wasn’t told about.

She told podcast Armchair Expert with Dax Shepard (and Monica Padman) the scene wasn’t in the script when she signed on, and she was terrified about going ahead with it.

“Oh God, I’m gonna be in trouble – but the love scene was not in the script,” Hayek, who would have been 28 at the time of filming, said.

“It was demanded by the studio when they saw the chemistry test. I had a really, really hard time with that… I don’t enjoy the scene,” she added.

She eventually agreed to film the scene in a closed-set environment.

“One of the things I was afraid of was Antonio – he was an absolute gentleman and so nice, and we’re still super close friends – but he was very free,” she said.

“It scared me that for him, it was like nothing. I started crying, and he was like, ‘Oh my God. You’re making me feel terrible.’ And I was so embarrassed that I was crying.”
