Dubious ain't a strong enough word for it.
This movie is an action adventure film produced by Jerry B.
Ofcourse he isn't perfect, some of his recent flicks have bombed. King Arthur failed because they took out the magic, so it's PG 13 rating didn't help it. And nobody wants to see his Romantic Comedies.
After all of the success that he has had with action adventure movies for the past few years I'm amazed that anyone is doubting POP boxoffice potential.
Prince of Persia doesn't even need good reviews to make huge bank. Most of Jerry B's movies get mixed to poor reviews and I think that Prince of Persia will get the same treatment.
I'm not saying it's a lock to be a success but I do think it's pretty much a lock to make over 100mil domestically. I wouldn't be suprised if it made over 250mil.
I remember when everybody under the sun thought that "awful looking-Johnny Depp is a sellout-Pirate movie" was going to fail...and it didn't. I remember when everyone thought that National Treasure was going to fail because it looked terrible, got bad reviews and Nic Cage is a hack and well, we already know how that story ends.
If G-Force can do 118mil I think that Prince of Persia can atleast match those numbers. Over the years I've learned to not doubt the power of Jerry Bruckheimer when it comes to these types of movies.
In conclusion:
Even if the movie fails at the boxoffice, it's going to fail big.
