Not just a pretty face
To a certain generation, Hedy Lamarr was the hypnotic star of "Samson and Delilah," one of the biggest blockbusters of the 1940s; to others, her name was a running joke in "Blazing Saddles."

Lives of the party
Those hoping for a rendition of the hokey pokey during this weekend's highly-touted nuptials will have to settle for "The Royal Wedding Live With Cord and Tish!" with vow-by-vow commentary from the characters made famous by "Saturday Night Live" alumni Will Ferrell and Molly Shannon.

"Fahrenheit 451" has never been successfully translated to the big screen, which is appropriate since the Ray Bradbury classic is all about the pleasures of reading. The latest adaptation doesn't buck the trend, despite the presence of red-hot Michael B. Jordan and Michael Shannon, in large part because so much of the drama takes place inside the head of the protagonist, who suddenly decides burning books isn't a great way to make a living.
