It is hard to believe that if the three actor sons of the late John Carradine each made 150 films, between them they would still not match the number their father appeared in. Carradine Snr, a character actor beyond compare, appeared in more than 500 films; many were bit parts but his face was seen in such classics as John Ford's Stagecoach and The Grapes Of Wrath, any number of Universal horror films and, after World War II, small roles in everything from Johnny Guitar to The Ten Commandments. His sons, David, Keith and Robert, have had busy enough careers but they have been far less distinguished. David, the oldest and best-known, could (along with Bruce Lee, of course) be said to be responsible for the worldwide popularity of martial arts. Such was the success of his character, Kane, the existential drifter in the 1972-74 series Kung Fu, that schools for the martial arts sprung up around the world. Since then, the sinewy David (who was previously married to Barbara Hershey) has taken to directing films, but with limited success. In the 70s and 80s, he made a number of movies but few were of note and nearly all cast him as the brooding, bruising loner. Safari 3000 (Pearl, 9.30pm) is a typical third-rate action adventure story that spews out every cliche ever made in a race film and every film located in Africa. Carradine plays Eddie Miles, a former Hollywood stunt driver trying to make it in the professional racing world. He enters the Africa International Rally; a 3,000-kilometre course through some of Africa's most hazardous terrain. Miles goes up against such opponents as jet-setter Count Lorenzo Borgia (Christopher Lee), who does not understand the possibility of losing. Also taking part in the race is JJ Dalton (Stockard Channing), a female reporter for Playboy magazine, who signs up as Miles' navigator; a daft role for a talented actress. Channing's film career has never quite ascended to the heights she could have aspired to. Though she has played some excellent character parts (in Smoke and an Oscar-nominated role in 1993's Six Degrees Of Separation ), the troubled-looking actress (whose most famous character was Rizzo in Grease ) achieved most of her success on Broadway, where she won a Tony. If you have any unwatched videos building up on top of the television, tonight is the night to watch them. And talking of cliched African locations . . . The difference between Chicago Hope and ER (Pearl, 8.30pm) is that the former (now screening on Mondays) has ridiculous plots involving doctors in deepest, darkest Africa (tribal paint and grass skirts in fact) dancing around fires to the sound of drums. Far-fetched though both hospital dramas may be, at least ER keeps its plots within the realms of possibility. Tonight, everyone is reassured to learn that another hospital, Southside, is closing down but its staff will be merged with County General's under new chief of staff Donald Anspaugh (John Aylward). Emergency room patients include a heavy woman on illegal drugs who becomes violent and two 15-year-olds who lost a condom while having sex. Panic is unleashed in One Foot In The Grave (World, 6.30pm) when Mrs Warboys suspects her husband is sleeping with another woman, Patrick and Pippa are invited to the Meldrews for a meal to patch up their recent quarrels and are wondering if they will return with their sanity intact. And then there is the nasty business that occurs at Victor's monthly magic society meeting.
