(CNN) -- CNN's Piers Morgan calls the on-screen relationship between "The King's Speech" actors Colin Firth and Geoffrey Rush "one of the great bromances we've ever seen in the movies." 

Firth, with his co-stars Geoffrey Rush and Helena Bonham Carter, joins Morgan tonight at 9 to talk about their movie, which leads the Oscar race and has dominated the awards shows so far. All three lead performers and the film itself are nominated for Academy Awards, scheduled to be presented February 27 in Hollywood. When Morgan asked Firth to describe Rush, the actor said, "I would describe him as my geisha girl." 

Geoffrey Rush appeared via satellite from Australia. Firth also called Rush "one of the most thrilling actors I've ever worked with. And I've seen him be howlingly funny and absolutely heartbreaking. He's got the whole spectrum covered." 

"We have been texting one another at various points to try and keep sane about the madness that's gone on around the film," said Rush. "And we do tend to refer to each other as Abelard and Eloise or Thelma and Louise." 

Firth talked about playing King George VI. "I fell in love with him completely," he said. "I love hidden, glorious and secret heroes. I'm not very interested in people with superpowers." 

The film centers on the relationship between George VI (who went by the name "Bertie") and his speech therapist, played by Rush, who worked with the king to overcome what Firth called a "crippling stammer." 

The actor called it an "athletic feat just to get to the end of a sentence" for the king.
