This is the first weekend in some time when we have more than a couple of new movies opening wide and it’s a weird one. We’ve got a powerhouse team of A-listers vying for first place against a 16 year-old musical phenom whose talent is, as least in the opinion of most adults and nearly all males, vastly less than phenomenal. Gotta love show biz.

If you’re betting on this weekend, you should probably demand some odds if your choice for the #1 spot is not “Just Go With It.” At least on paper, this is a smartly designed movie in terms of attracting a mass audience. To be stereotypical about it, there’s a little romance for the women, and little raunchy comedy for the men and a slightly unusual pairing of rom-com reliable Jennifer Aniston and raunch-com superstar Adam Sandler.

The cinematic seers and soothsayers referenced over at the L.A. Times and THR differ only very slightly in suggesting that the comedy from Sony/Columbia, will do something in the neighborhood of $30 million, or perhaps a bit more. Neither Aniston nor Sandler have ever been critical darlings and their latest outing isn’t changing that.

The strange aspect of this is that the film is an unheralded remake of 1969’s “Cactus Flower,” which had a screenplay adapted by the later-career collaborator of Billy Wilder, I.A.L. Diamond, and starred Walter Matthau and my hugest crush ever, Ingrid Bergman, in the roles now inhabited by Sandler and Anniston. I’ve liked both Sandler and Anniston in movies from time to time but, my God, talk about devolution. I’ve never seen model-turned-actress Brooklyn Decker in anything, so I’ll spare her the comparison to Goldie Hawn, who won an Oscar for her role.

Meanwhile, there’s more than a little mystery about just how much Paramount’s “Justin Beiber: Never Say Never” will make. Apparently, Beiber’s very young, very female fan base is defying marketers’ ability to measure and predict the results for this 3D docu-concert flick. The really weird part of all this is that, of all four movies being released this week, the biographical documentary has the best reviews with a respectable enough 64% Fresh rating over a Rotten Tomatoes as of this writing. A sad commentary, perhaps, or just another sign of the show biz apocalypse. Could this film actually top the week’s box office? Probably not, but never say “never.”

Gnomeo and JulietNext is the 3D animated comedy, “Gnomeo and Juliet.” Disney apparently wanted to keep this one at arm’s length and is releasing it through Touchstone, usually reserved for racier properties, despite the film’s G-rating. My hunch is that animation chief John Lasseter felt the rom-com suitable for the very young wasn’t quite up to snuff all around. The reviews, however, are not completely awful and the voice cast — which includes James McAvoy, Emily Blunt, Sir Michael Caine, Dame Maggie Smith and, in a voice-acting debut, Jason Statham — is beyond first rate. It also boasts music by Elton John and parents can also feel like they’re prepping their kids for Shakespeare even if this is comedy and not tragedy. So, the guess of $15-20 million seems reasonable enough to me.

Finally, we’ve got swords, sandals, Channing Tatum, and Jamie Bell in “The Eagle.” No one seems very excited about this costume actioner and that non-excitement seems to be communicating itself through some underwhelming box office guesses to match its deeply “meh” notices.

In limited release in some 16 theaters according to Box Office Mojo, the world always needs a good, or half-way decent, comedy and the large majority of critics seem to agree that “Cedar Rapids” is just that. With a cast of tip-top comedy veterans including Ed Helms, John C. Reilly, and Anne Heche, among others, it’s hard not to have an upbeat attitude about this one.
