A ROMANTIC COMEDY about an aging couple played by Meryl Streep and Tommy Lee Jones, Hope Springs doesn't exactly sound like popular fodder. But let's not forget that BOTH Streep and Jones are Oscar winners (with Streep nominated for more "Best Leading Actress" Oscars than anyone else, um, ever). The director here is romantic-comedy vet David Frankel, of The Devil Wears Prada, who is also an Oscar and Emmy winner himself. So, not to overexaggerate here, but the billing is pretty Academy-proof for this one. Unfortunately, that doesn't always bring the big bucks. The movie's got an awkward premise that most of us have seen before: aging couple's not intimate anymore, so they go to a couple's therapist (hi, Steve Carrell) who turns their romance back on. Frankel's last movie, The Big Year, only made $3M in its opening weekend. The Devil Wears Prada did much better, though, at $27M, and we think Meryl Streep had more than a little bit to do with that. Our forecast for Hope Springs? A cool $20 million. It won't beat out the other comedy opening in the same weekend (The Campaign), but it may pick up straggler audiences looking for a more, ahem, mature comedy.
