Tom Cruise is a name recognition itself, and it has Russel Crowe, and The Mummy is a name recognition, the trilogy was pretty popular, and if they play the shared universe card - you might get a look at Johnny Depp as well. I think they might advertise it as a family adventure film, they ditched the all out horror angle, I think.
So I'm not expecting MI 60M+, nor knocking out WW and take top spot, but it should do much better than Edge of Tomorrow and that can take a bit out of WW's legs, and then Transformers and Minions are in the same month I think, so I'm concerned for WW's legs.
