Jessica Alba described getting naked in Fantastic Four as "awful and very humiliating".

Weeks after shooting wrapped, the 44-year-old actress "regretted" filming the scene - which saw her character Sue Storm appeared in her birthday suit on a bridge - because she grew up with a "pretty conservative" family and is a "modest person".

During an In Conversation With event at the Red Sea International Film Festival in Jeddah, Saudi Arabia, Jessica told host Wendy Mitchell: "I hated that scene when they brought her back on the bridge, and she had to be naked on the bridge.

"It was awful and very humiliating in real life, because I grew up with a pretty conservative family, and I'm a modest person and so it was something I was like, 'Oh, no, not this.' I regretted that scene for weeks."

The star enjoyed some of the stunts in the 2005 superhero movie, but would not do them now.

Jessica said: "Getting ricocheted back into the wall, getting blasted, that was always fun, that was fun back then. But now, thank you I don't want to get whiplash."

Apart from the naked scene in Fantastic Four, Jessica "loved" playing Sue Storm because the character defied gender stereotypes.

Jessica said: "She was a woman I looked up to. She was very maternal and very kind, but also not a pushover; she spoke her mind.

"She had a great moral compass. No matter who you are, you can look up to her. Oftentimes, the women in these stories need to be saved by a guy or the villain, the problem in the story. This was back then. It's different now."

And later in the conversation with Wendy, Jessica - who owns production company, Lady Metalmark Entertainment - shared she is trying to "change minds" with regard to diversity on screen.

Jessica - who noted she does not "blame Hollywood" - explained: "Growing up, I didn't see a lot of diversity in storytelling.

"When you have a lot of white guys in charge, they feel most comfortable telling stories through their lens. They don't know you.

"They didn't grow up with a woman who grew up like me. Frankly, many of them didn't have women [in their lives] who were strong, not just running the household but making an income.

"We still don't have a lot of female leadership, but as a woman of color, I don't see the boundaries that they may see."
