New movies like "Plane" and "House Party" were no match for "Avatar: The Way of Water" and the killer doll horror "M3GAN" at the box office this weekend. The two holdovers topped the charts again according to studio estimates Sunday.

In first place for the fifth weekend in a row was James Cameron's "Avatar" sequel, which added an estimated $31.1 million through Sunday. That total will likely balloon to $38.5 million by the end of Monday's Martin Luther King holiday. As of Sunday, the film's domestic total now rests at $562.9 million (the 13th biggest of all time) and its global total is $1.89 billion. "Avatar 2" needs to pass $1.92 billion to trump "Spider-Man: No Way Home," which is currently the sixth highest grossing film of all time globally.
