Tom Hiddleston and Elizabeth Olsen have starred in Marvel movies before as the super-villain Loki and the new Avenger Scarlet Witch, respectively. The actor and the actress were promoting the Hank Williams biopic movie, "I Saw the Light" at the Toronto International Film Festival when they were interviewed by the Hollywood Reporter.

In what would be an unusual match-up, Hiddleston and Olsen were asked who would win in a battle between two of the most powerful characters in the Marvel universe.

Naturally, both Hiddleston and Olsen chose their characters.

"I think Scarlet Witch would win - she's one of the most powerful people in the universe," Olsen says.

Writer-director Marc Abraham agreed with Olsen and took her side in the fantasy battle.

"I'm betting on Scarlet Witch."

In response, Hiddleston, of course took his Asgardian alter ego's side.

"The thing is, you're dealing with someone who's a witch, which is admittedly impressive biographically.

But you put that up against a god, I'm just not sure that there's a fair contest. He's an immortal being, so my chips are firmly in Loki's corner."

Watch the entertaining exchange between the actors below.

It is said that great art is the product of struggle and hardship, and truer words have never been spoken when it comes to the life and music of Hank Williams. "I Saw the Light" showcases the meteoric rise to fame and fortune of one of the greatest and most influential country singers of all time, but it also delves into the dark and troubled life that existed away from the spotlight. From the drug & alcohol addictions to troubled relationships to the string of broken hearts he left in his wake, it was Hank Williams' tumultuous existence that not only fueled his powerful lyrics and heartfelt songs, but also brought his life to its tragically short end.

"I Saw the Light" will be released in theaters on Nov. 27, 2015.
