Joss Whedon has responded to controversy surrounding his recent tweet in which he called a recent "Jurassic World" clip "sexist." Speaking to Variety when attending "Avengers: Age of Ultron" premiere in Los Angeles on Monday, April 13, Joss said he regretted his act.

"I shouldn't have tweeted it," he told the site, "I don't ever say things about other people's work that are negative. That's bad form. It's not what a gentleman would do." Despite his regret of sending the tweet, the 50-year-old filmmaker hasn't deleted the tweet and stands by his judgement, admitting that the clip made him "frustrated."

He said, "I forgot that I don't do that because I was frustrated. I felt like I was seeing something that was problematic. What I said is pretty clear, but I think it was the wrong venue for me to be saying that. That's dinner party conversation."

On Friday, April 10, when the Mary Sue tweeted, "We're too busy fanning ourselves to talk more about Chris Pratt in this #JurassicWorld clip," Joss replied to the site, "...and I'm too busy wishing this clip wasn't 70's era sexist. She's a stiff, he's a life-force - really? Still?"

The clip in question shows Chris Pratt's character Owen and Bryce Dallas Howard's character Beth discussing the ethical issues of cloning dinosaurs. They are also engaged in a banter where he makes fun of her for being too uptight and she criticizes his outfit.
