Will Smith is all smiles again ... he and Jada Pinkett Smith were back doing movie star stuff for the premiere of the new film days after he called his Oscars slap on Chris Rock a burst of anger years in the making.
Will and Jada got all done up Wednesday night in Westwood where they held the "Emancipation" premiere -- they posed for the photogs on their way into the theater and held onto each other tightly.
He also made a plea to the audience, telling them to be nice to each other ... because you never know what another person's going through, but he noted that didn't justify his behavior.
FYI -- Will's performance in "Emancipation" might be up for awards. He told Trevor he fears the film might get snubbed due to his behavior. Remember, he's banned from attending the Oscars for 10 years, although he can still be nominated and even win.
