LOS ANGELES — Over the bustling post-Christmas weekend, Peter Jackson’s “The Hobbit: The Desolation of Smaug” continued to lead the box office, landing in the No. 1 slot for the third weekend in a row.

The Warner Bros. prequel earned $30 million, bringing the domestic gross to $190.3 million.

Disney’s animated adventure, “Frozen,” took the No. 2 position, earning $28.9 million over the weekend and $248.4 million domestically after six weeks at the multiplex.

“‘Frozen’ probably had the best release date of the year because they positioned themselves to completely dominate the family film marketplace over the holidays,” said box-office analyst Paul Dergarabedian. “To be No. 2 in its sixth week is a total reflection of that.”

“Hobbit,” “really contributed to this record box office that we have at the end of the year,” he added. “With ‘Hobbit’ and ‘Frozen,’ we are talking $450 million at the box office between those two films alone. They are absolutely killing it here at the end of the year.”

Estimated sales were:

1. “The Hobbit: The Desolation of Smaug,” $30 million.

2. “Frozen,” $28.9 million.

3. “Anchorman 2: The Legend Continues,” $20.2 million.

5. “The Wolf of Wall Street,” $19 million.

6. “Saving Mr. Banks,” $14.3 million.

7. “The Secret Life of Walter Mitty,” $13 million.
