It’s quite a sacrilege for Les Miserables fans to hear this, but apparently Amanda Seyfried [who plays Cosette in the movie] and Hugh Jackman [who plays Jean Valjean] jokingly sexualized their scenes together.

In an interview with Vanity Fair, she talked about the movie and Jackman, saying, “There is nothing bad to say about Hugh. He isn’t human. I bet you anything he’s got some kind of superhuman capabilities, beyond just being just the kindest, gentlest soul I’ve come across.”
She also adds that they both share an inappropriate sense of humor and as a joke, invented alternative storylines that change their character’s relationship into something not so innocent. “We sexualized everything as much as we could. It was really funny, the moments we could find . . . It’s like every movie has another version, another satirical version of itself.”

She also talks about her other movie ‘Lovelace’ and the challenges it presented, saying, “We were doing a scene where I was supposed to be going down on Peter Sarsgaard. We used a popsicle, and I had my arms covering the popsicle. It was footage that he was going to show the Deep Throat guy, to get her into the movie, to get her cast. I was laughing hysterically throughout. I couldn’t stop laughing.”
