While her character boasts powers of invisibility, there would be no blending in for Kate Mara on Saturday.

The 32-year-old was dangerously close to stealing the spotlight when she arrived in a low-cut sage green dress that put her ample assets on show.

Kate drummed up interest for the film at Sirius XM's Entertainment Weekly Radio Channel at Comic-Con beside cast mates Miles Teller, 28, Jamie Bell, 29, Toby Kebbell, 33, and Michael B. Jordan, 28.

Kate was poised to impress with her flawlessly applied makeup and chic hairdo.

The House Of Cards star beamed with her cropped strands slicked dramatically over her head, while pops of light pink blush softened the look. 

Kate was certain to stand out with her bright gold bracelet as she plugged the upcoming comic book film.

While chatting with the hosts, Kate revealed she knew little about the famous franchise prior to production. 

However, the good company Kate was surrounded by proved to be advantageous when she approached her role.   

'I wasn't very familiar with the Fantastic Four before we started,' the actress admitted during her chat.

'But, like Toby said, it was all there in the script and Josh obviously has a lot of knowledge on it, and so I just trusted his thoughts on it and Simon Kinberg as well.'

During a recent interview with Flare, Kate revealed how the cast's chemistry livened up the mood during 'intense' moments on the set.

'The movie is very intense, so the set was an intense environment. But because of our dynamic, there was a lot of joking around,' she said.

'When you’re having to emote a certain kind of energy and vibe all day, you need to joke around to let off some steam.' 

In the forthcoming Fantastic Four reboot, Miles will play Reed Richards (Mr. Fantastic), whose abilities include stretching his skin.

The latest installment of the super heroes sees the team infected with new-found powers after an experimental journey goes wrong. 

Fantastic Four will hit U.S. cinemas on August 7.
