The Creed star will reportedly play Chris Hemsworth's love interest in Thor: Ragnarok, according to Her character will be a superheroine, but details surrounding her name and powers have not been released.

The movie, which is scheduled to begin filming in July (16), will be directed by Taika Waititi. It is slated for release in November, 2017, and will also also feature Tom Hiddleston, Cate Blanchett, Jamie Alexander, Mark Ruffalo and Lou Ferrigno.

Reports suggest Tessa she will also appear in other Marvel Studios films. The next movie to be released by the comic book giant will be Captain America: Civil War next month (May16), and the blockbuster's star Chris Evans feels moviemakers need to continue making the movies.

"Let's keep going, let's let the wave get bigger and bigger, it's not like they're making bad movies; they're making great movies and if you want to put them in this superhero box you can but they're good movies," he told America's Variety magazine. "They've (Marvel Studios) got a monopoly on it, they're doing it and no one else can try and copy it."

The Marvel films have enjoyed a run of critical and box office success since the first instalment in the franchise, Iron Man, hit screens in 2008.

However, they now face competition for comic book fans loyalties from DC Comics and Warner Bros.' new Justice League series, which will see popular characters including Superman, Batman and Wonder Woman join forces on screen in a similar way to characters from the Marvel universe.

The second film in that franchise, Batman v Superman: Dawn of Justice, opened last month (Mar16) and topped the U.S. and U.K. box office charts despite a deluge of bad reviews.

Despite the new challengers, Marvel Studios boss Kevin Feige still believes his slate of superheroes, which as well as Chris' character includes Robert Downey, Jr. as Iron Man, Scarlett Johansson as The Black Widow and Mark Ruffalo as The Hulk, are the ones to beat, saying, "There has never been an ensemble like this in cinematic history."
