Erratic and capricious. Is pleased by most blue things. Likes to dream of tweed, and black cats, and coffee, and out-of-print novels. Badly whistles Belle & Sebastian songs when nervous. Inept conversationalist. Somewhat adept writer.
Bill Murray genuinely found Ronnie McCawley and Keith McCawley (the two actors playing his sons and who were very much like their screen characters) annoying and many of the scenes where he lashes out at them and insults them were improvised.
