James Woods is suing a guy for something every celebrity has to deal with every day -- someone talking trash on Twitter ... and he's gunning for $10 million. Woods is going after a guy who goes by the name of Abe List. Woods claims List trashed his good name several times -- with tweets calling him a "prick," "joke," "scum," "clown-boy" ... but crossed the line when he accused the star of being a "cocaine addict." Woods claims his reputation was damaged to the tune of $10 mil.
