The new Dreamgirls trailer is good stuff, but it doesn’t deliver the same pizazz I’ve gotten out of those 20-minute reels shown at those special press presentations — one several weeks ago at the Pacific Design Center, and an earlier one at the Cannes Film Festival last May. The unspoken fear is that the original Dreamgirls stage musical in the early ’80s had a weak story (a friend who saw it way back when says this was the main complaint from the New York theatre critics), and that if Bill Condon‘s feature runs into any kind of flak, it’ll be from this.
