The Oscar-winning actor was promoting his own new movie "Sully" at the Telluride Film Festival when he interrupted the Q & A to extol the virtues of the new musical, which has been directed by Damien Chazelle, reported Female First.
"This is not a movie that falls into some sort of trend. I think it is going to be a test of the broader national audience, because it has none of the things that major studios want," Hanks said.
The 60-year-old actor said he is impressed the project got made because it is so different to anything else around and he is thankful studio bosses ignored trends to green light the movie.
"I like to think we approach movies the same way we approach being members of the audience in that you just want to see something you have never seen before. It's funny.
"We all understand the business aspects of it. It's cruel and it's backbreaking and take-no-prisoners. But there's always that chance where the audience sees something that is brand new, that they never expected, and embraces it, and celebrates it," he said.
