It’s Hollywood awards season when top actors, directors and producers — plus their reps, their mothers, their kids and their kids’ reps — are reduced to raw nerves. “Les Misérables” director Tom Hooper learned four minutes before a Michael’s lunch reception for his movie musical yesterday that he’d made the cut for a Directors Guild of America Award nomination with Steven Spielberg, Ben Affleck, Kathryn Bigelow and Ang Lee. “It was 12 o’clock, then 12:30,” Hooper said of waiting at his hotel for any news from DGA head Taylor Hackford, who customarily calls nominees before an announcement. “I was exploring in my mind the relief of not being nominated, acting out appearing at the lunch with tremendous graciousness,” he joked. Hooper, who seems perpetually calm in an extremely English way, admitted that before he won a 2011 Oscar for “The King’s Speech,” he was a “dark mass of nerves” over making his own speech “in front of half a billion people. That made me a lot more compassionate with actors.” He said even unflappable Hugh Jackman admitted on the “Les Miz” set to getting performance anxiety. Also at the lunch were Eddie Redmayne, Gayle King, Deborah Roberts and Lara Spencer.
