This feat would make it the first $100-million opener of 2017 (beating out the $88-million opening of “Logan” as the year’s best so far), as well as the highest March opener ever, edging just past the $166 million grossed by “Batman v. Superman: Dawn of Justice” last year. It would also shatter the $135-million record held by “Finding Dory” for the largest opening of a PG-rated movie.
