Perhaps John Goodman's arthritis has put him in a bad mood.
The 60-year-old "Argo" star, who went on a strict diet in 2009 and ended up losing 100 lbs. in order to save his knees, was not particularly pleased when a British journalist recently pried into his past alcoholism.

The Guardian's Xan Brooks interviewed Goodman about starring in Ben Affleck's new film and appeared to get off on the wrong foot by bringing up the actor's drinking problem, which landed Goodman in rehab in 2007.
"It was 30 years of a disease that was taking its toll on everyone around me, and it had got to the point where, every time I did it, it was becoming more and more debilitating," Goodman said. "It was life or death. It was time to stop."
After Brooks asked the thesp how alcohol affected his acting, Goodman replied, "Temperament. Memory. Depression," before reportedly turning to stare at the wall in silence for an extended period of time.
"This is not something I want to chat about to sell a f---ing movie. You understand?" Goodman eventually said. He then quickly apologized. "I'm sorry, I'm very tired. It seems a little cheap to me."

The journalist himself apologized for offending his interviewee.
"It's not your fault, it's the process," Goodman replied. "I can't just waltz in here and talk about the movie; I have to dredge up some very unpleasant things, and it's just not worth it."
Apparently, David Letterman is the only one who can get a laugh out of Goodman:
