One of the most entertaining pool stories I've ever heard. The iguana jumps off his shoulder and chases the 9-ball into the pocket. Freaking hilarious. What a character.
That whole story is worthy of a movie scene. Along with the Wimpy Lassiter story with the girl he was smitten for told in Danny D's book.
Someone needs to write a semi-fiction pool movie following a low end hustler/pro (nowhere near the best, more of a shortstop who is simply part of the scene) much like McGoorty, and then write in alot of the coolest scenes from the last 60 or 70 years following the game from the 1930's until the 90's or so.
Write the screenplay as a recollection of the past (start with an old man in a pool hall watching pool on TV and watching a couple goofy late teens kids trash talking and gambling for $5 a game, circa 1990). It is mid day, the place is largely dead, he is just sitting there drinking coffee, the bartender just cleaning up the bar and asking him if he wants "anything more then just coffee". One of the cocky kids asks him to gamble, knowing the 80 year old man will not play. On getting the known response the kids laughs and walks back to his table and friend. The old man sits there, listening to the laughing, and the scene fades to 1930's Chicago or the like and so, back to his youth.
Go through the era's of pool, introduce characters through the eyes of the old man as you follow him through his life and experiences, the cool scenes, the legendary players, the classic hustles and life on the road. Use the music of the era's, great art direction with the cars, the style of 1960's Los Angeles when he is there and the Beach Boys are huge on the radio.
Don't make the guy a star, make him a decent player, a road player good enough to beat the average guys, good enough to be known by most of the players, but at that level where he is no match for the truly top players. Don't make the movie about him, make it about the game, the other people in it, the scenes that take place, just make the old guy the eyes and memories via which the things are seen.
