Baltimoreans who've hoped that Adam Shankman would return to big-screen musicals after the bang-up job he did with "Hairspray" now have "Rock of Ages" to look forward to. Shankman is directing the movie version of the Broadway hit built around 1980s rock hits by Styx, Journey, Bon Jovi, Twisted Sister, "and many more!" (as the above stage trailer promises). According to Total Film, Shankman tweeted on Saturday, "Can't wait to start #rockofagesmovie. Julianne Hough, alec Baldwin, Mary j Blige, Tom cruise confirmed. I love my cast. More to come."
