“Well, breakdowns come and breakdowns go — what are you gonna do about it, that’s what I’d like to know.” For Larry Gopnik (Michael Stuhlbarg), a physics professor in the Midwest circa 1967, it’s decision time in the “striking” brand-new trailer for Joel and Ethan Coen’s A Serious Man, also starring Sari Lennick, Richard Kind, Fred Melamed, Aaron Wolff, Jessica McManus, and Adam Arkin. Always good to see the brothers back in town.
