Oddball actor Gary Busey has been warned to be on his best behaviour at an upcoming Oscar night bash on Sunday following previous run-ins with fellow celebrity party-goers.



The stars will be out in force in Hollywood on Sunday as the town hosts its biggest event of the year, the Academy Awards, and a series of glitzy parties are held so the industry can toast the ceremony's big winners.



Sports agent Norby Walters throws the Night of 100 Stars gathering, and he has already reached out to Busey to ensure he does not act up at the bash - or he'll face a lifetime ban.



Walters tells the New York Daily News, "I called him at his house last week and told him, 'Be warned, if you get a bit nutsy (crazy), you will get kicked out.'



"He's not a bad guy, just nutsy. It's just that he growls and barks. I warned him if you growl, get in anybody's face and if you have anything other than a nice chat, then you will never be invited back again. 'Here's the deal: The hotel says they will not tolerate your bulls**t. So sit there and enjoy hanging out with your old friends.'"
