Broadway Tribute: Catherine Zeta-Jones, Jennifer Hudson, and More Perform at the 2013 Oscars

Midway through the Academy Awards, stars Catherine Zeta-Jones, Jennifer Hudson, and nearly the entire cast of Les Miserables, performed an amazing Broadway tribute to award-winning films, some of which have been nominated for Oscars this evening.

Catherine Zeta-Jones kicked off the tribute with a full-costumed, song and dance performance of "All That Jazz" from 2002's Chicago, for which the actress was nominated for Best Supporting Actress. Her performance was entertaining, but JHud stole the show with her standing ovation-inducing performance of Dreamgirls' "I'm Not Going," for which she won Best Supporting Actress in 2006.

Members of the Les Miserables cast, such as Hugh Jackman and Anne Hathaway, both nominated tonight, closed the tribute with a performance of "Suddenly." Russell Crowe received encouraging applause (perhaps some sympathy claps after critics slammed his singing in the film) and the entire cast received a standing ovation. Sidenote: Did anyone else notice that Samantha Barks looked freakishly like Kate Middleton? Especially in that conservative, royal family approval-worthy blue gown...
