It was a Thanksgiving feast for the teenage wizard, as Harry Potter and the Deathly Hallows — Part 1 led the box office on Thursday by engulfing $11.5 million, according to early estimates. That result brings the PG-13 fantasy film’s seven-day gross to $170 million. Not far behind on Thanksgiving, and performing stronger than expected, was Disney’s animated musical Tangled, which earned $8.1 million.
