Tom Cruise new movie flops at the box office. What else is new? Did they really expect this movie to do any good? Just because they nailed Tom Cruise crazy ass for the superstar in the movie it won't push sales. Tom Cruise isn't the heavyweight he use to be..

Rock of Ages, from New Line and Warner Bros., received a so-so B CinemaScore. The movie came in far behind Shankman and New Line's 2007 Hairspray and Universal's 2008 Mamma Mia! Both of those movies, likewise based on hit Broadway musicals, opened just north of $25 million.

One issue for Rock of Ages was that it failed to rally younger moviegoers, despite leads Julianne Hough and Diego Boneta. Nearly 75 percent of the audience was over age 25, the demo that most relates to the film's music. Females made up the majority of those buying tickets, or 62 percent.

"The numbers aren't great. It's hard to fathom since the movie plays so well," Warner Bros. president of domestic distribution Dan Fellman said. "I'm still optimistic we can overperform during the week because of women."

Rock of Ages also fell flat overseas, where it grossed a sobering $4.1 million from 10 markets. It came in No. 3 in the U.K. and Australia with $1.7 million and $1.4 million, respectively
