Marvel's Victoria Alonso was the keynote speaker at yesterday's Visual Effects Society Production Summit at the W Hollywood, where she revealed that the highly-anticipated sequel Avengers: Age of Ultron has over 3,000 visual effects shots, the most of any movie in Marvel history. This breaks the studio's record of 2,750 VFX shots held by this year's Guardians of the Galaxy, while Captain America: The Winter Soldier had over 2,500 visual effects shots.

She also revealed that the studio will use between seven and 12 visual effects companies in five to seven different countries for Avengers: Age of Ultron, which is currently in post-production. She also addressed the need to hire more women in the visual effects industry.

"There's a lot of you boys out there. Where are the girls? You need to get them here. It's better when it's 50/50. It's okay to allow the ladies in; they are talented and bring you balance. We are better as a team if you have balance. This a tough road for women, not because it is a world of men, but because it takes a certain amount of time to be in a supervisory position, and by that time you are having to make a decision about having children or not. Which means you have to take a break. If you take a break, you're out of the game, and once you're out of the game, it's hard to get back in the game."

The Marvel executive also spoke about when Marvel will make a female-lead superhero movie, in the wake of Warner Bros.' announcement this week that the studio is moving forward with a Wonder Woman movie starring Gal Gadot.

"If it were up to me, it would be today. We have so much pressure internally for everything we do, we don't need outside pressure. We are always so hard on ourselves. The success of superheroes, whether ours or others, is success for all of us. But I will be honored to be part of a woman leading the way."
