The Lion King’ prequel had a bumpy start, debuting with a meager $35 million. While it's expected to make up some ground, 'Mufasa' still has ways to go.

Mufasa benefits from strong international sales, while Sonic 3 leverages its video game roots and family appeal.

R-rated movie NOSFERTU made $40.3 million in its first five days, and A COMPLETE UNKNOWN, also rated R, made nearly three times less than MUFASA and SONIC in its first five days at $23.2 million.
