NEW YORK CITY: 'The Nun 2' and 'A Haunting in Venice' virtually tied for the top spot in United States and Canadian theaters over the weekend, with a slight edge carrying the horror sequel over the latest Hercule Poirot mystery, studio estimates showed on Sunday.

In its second weekend of release, Warner Bros.' 'The Nun 2,' a spinoff from the studio's lucrative 'Conjuring' franchise, grossed $14.7 million. If numbers hold, that will give 'The Nun 2' (up to $56.5 million total and $158.8 million worldwide) the No. 1 spot at the box office for the second straight week.
