Shares of DreamWorks Animation SKG Inc. fell sharply in Monday trading after a disappointing opening weekend for the Glendale animation studio’s “How to Train Your Dragon 2.”

The sequel opened in theaters Friday and took in about $50 million at the domestic box office, but some analysts had expected the film to make $60 million or more. The film’s distributor, 21th Century Fox, had cautioned that sales would be closer to $50 million.

The top spot at the U.S. box office went to Sony’s “22 Jump Street,” which made $60 million.

DreamWorks Animation shares fell 11 percent to $24.35 in Monday trading on the Nasdaq.
