Downward Spiral! Bloated & ‘Bizarre’ Johnny Depp Shocks Fans At Film Festival

Is Johnny Depp OK? The actor's increasingly erratic behavior is worrying observers, RadarOnline.com has learned, as award season pressures continue to mount.

Depp's appearance stunned observers at the Palm Springs International Film Festival in Palm Springs, California, on January 2, 2015.

Though he made a good impression with locals by signing autographs with fans on the red carpet, the Black Mass star's bloated, disheveled appearance was difficult to ignore.

One observer told Radar, "He was very friendly but almost unrecognizable! He looked to have put on a good 30 pounds at least."

The source continued, "His hair was a greasy mess, and his teeth were yellowed too. It was pretty shocking." Joked the source, "He looked more like Marlon Brando than Johnny Depp!"

Inside, Depp, 52, raised eyebrows among the industry insiders with odd behavior. "During the dinner, he went over to Christian Bale's table and squatted on the floor talking to him," another eyewitness added.

But he seemed to have lost the gift of gab by the time he got on stage to receive his award. Instead of a traditional acceptance speech, "He kind of mumbled, 'How was the beef?'" the source said. "He seemed really confused and rambling and then just ended abruptly by saying 'It's over with, that's it,' before just walking off. People were kind of looking at each other like, 'What just happened?' It was bizarre."

Depp was later a no-show at the after-party at the Parker hotel. And insiders tell Radar this is just the latest example of his troubling professional appearances. At one recent photoshoot, a source told Radar, "He showed up totally worse for the wear and seemingly intoxicated. He was stumbling, unable to engage in a coherent conversation, nearly impossible to work with. It took the team several hours to get him presentable."

In June, Radar reported that Depp had hired a sober coach after an intervention from Disney execs who were concerned his boozing could torpedo the next Pirates of the Caribbean movie. Story developing.
