The Cusacks have been busy of late, as several new trailers attest: John Cusack the crack assassin flounders in the Emerald City in the new preview for War, Inc. (a.k.a. Grosse Point Blank meets Lord of War), also starring sister Joan, Marisa Tomei, Hillary Duff, and Ben Kingsley. John Cusack the cranky sci-fi writer adopts a problem kid with a heart of gold in the trailer for Martian Child (a film you’d have to pay me to see), also starring sister Joan, Amanda Peet, Richard Schiff, and Oliver Platt. And, though it’s been on the web awhile now, John Cusack the depressed seeker of paranormal activity bites off more than he can chew in the trailer for Mikael Hafstrom’s 1408 (from the Stephen King story), also starring Samuel Jackson, Mary McCormack…and sister Joan? Well, not this time. Perhaps they can add her as a CGI ghost or something.
