I'm thinking $25m as well. Should know within a couple hours.
This year so far has been so exciting box office wise! American Sniper takes Jan Record, Fifty Shades takes Feb Record, March does decent with Cinderella, Home, and Insurgent but definitely no records, Furious 7 puts the year back on track with April record, and now Avengers:AoU!
I know I'm not saying anything new, buts it's fun to reflect.
