LOS ANGELES, March 18 — For a second weekend running Kung Fu Panda 4 battled its way to the top of the North American box office, narrowly edging out Dune: Part Two, according to industry watcher Exhibitor Relations.

Panda, a martial arts comedy from Universal and DreamWorks Animation, took in an estimated US$30 million for the Friday-through-Sunday period, while the Warner Bros. Dune sequel, about war and survival in a sand-covered planet inhabited by giant worms, earned a respectable US$29.1 million.
