Don Giovanni now comes with a bucket of popcorn. Four years after first taking opera productions to the movie theater, the Metropolitan Opera has announced that it is bringing its "Live in HD" broadcasts to 100 additional U.S. venues.

Will audiences abandon live opera altogether and head to the movie theater instead? Blogger James Jorden, who writes the opera blog Parterre Box, doesn't think so.

"I've heard a little bit of anecdotal evidence that maybe there are some people who are doing that," Jordan says. "I honestly don’t think that it's putting a big dent in anyone’s live opera going. If anything, I think the HD broadcasts are developing an audience who are interested in the art form."

Last year, the audience for the Met's movie telecasts was three times the attendance at the opera house.
