I know I am asking a difficult film trivia question when my colleague, Donal Scully, cannot get it right. He has one of those microscopic memories that allows him to recall instantly the year almost any film was made and, in most cases, detail the characters, the actors who played them, the lines they said (accent in tact), and when and to whom they said them. It's wonderful to sit next to him because I can check my 'facts' safe in the knowledge that he is more likely to be correct than Halliwell's bible of film. So I was thrilled when I was able to get this one past him. Which real character have Kurt Russell and Val Kilmer, the stars of Tombstone (Pearl, 9.30pm), both portrayed in motion pictures (have you noticed how Hollywood actors always call them that?) and what were the films? Donal instantly piped out Doc Holliday, another cried Wyatt Earp. Both were wrong; the answer is Elvis Presley. Russell played The King in Elvis, John Carpenter's made-for-TV biopic that launched him as an adult star, breaking the clean-cut Disney image he had earned as a child actor. Russell starred as the ghost of Elvis in True Romance, the catch being that his face was never seen. The connection does not end there; Russell also starred alongside Elvis in the 1963 film, It Happened At The World's Fair. And it was as an Elvis-like rock'n roll spy in Top Secret that first pushed Kilmer, a Juillard-trained actor, into the public eye, though it took him seven years (and several starring films) before he attained real stardom as the self-destructive rock singer Jim Morrison in 1991's The Doors. In Tombstone, Russell plays Wyatt Earp to Kilmer's tubercular Doc Holliday. Earp tries to leave his violent days behind him by moving to Tombstone with his two brothers but the murderous gang called The Cowboys (headed by Powers Boothe as Curly Bill Brocius and Michael Beihn as Johnny Ringo) dictates otherwise. It's a throughly overblown Western but given the historic and oft-told story it manages to carry it well. Russell's performance is strong and Kilmer's endearingly eccentric. Incidentally, the real Earp's fifth cousin, naturally called Wyatt, plays Billy Claiborne. Robert Mitchum narrates. It's going to take snow in Hong Kong to stop me watching Chicago Hope on Monday nights, no matter how daft it is getting. This week, we watched Shutt and his new, gay research partner eyeing other members of the hospital staff walking around in the buff (or, at least, that's how they imagined them). My only hope is that if ER (Pearl, 8.30pm) gets as silly it will be George Clooney's derriere disappearing off camera that we get to spy. One doubts it. In tonight's episode, Lewis invites Greene on a vacation to Hawaii and he hopes she wants to be romantic with him. Secretly, she does but when Greene cautiously decides not to join her, she feels foolish. New chief of staff Anspaugh annoys everyone with his silly ideas and overly strict efficiency standards. Because of the Southside hospital closing, patient load is expected to rise by 30 per cent and Anspaugh vows to punish whoever treats the least amount of patients. Benton tells Jeanie not to risk mixing her HIV-infected blood with the patients' and warns her to stay out of his operating room. Among the emergency room cases is a drunken man who claims he was attacked by a kangaroo and Hathaway's former teacher who thinks she is a doctor. And Ross, who seems to practise everything but medicine, must advise a 15-year-old girl with gonorrhea not to have casual sex, then has sex with a lab technician in an examination room.
