Former Batman star Michael Keaton’s life-as-art turn as a washed-up superhero proved award season gold this morning, with seven nominations for the statuettes seen as Oscar precursors. Richard Linklater’s childhood-spanning “Boyhood,” along with “The Imitation Game,” had five each. On TV, “House of Cards” and “Downton Abbey” garnered nods, but the snubs hurt. “Modern Family,” “The Walking Dead,” even “Sons of Anarchy,” which rode off into the series sunset this week, got no love. The awards are doled out Jan. 11.
