Can't wait until Oscar night for one of those montages of movie highlights? If you need a fix of thematically linked film clips, rent Houseguest. Foreshadowing a scene in which he gets roughed up by two toughs, channel-surfing Kevin Franklin (Sinbad) finds nothing on TV except shots of people hitting each other in the face. Watch carefully for excerpts from such TV series as Star Trek, Cheers, and The Simpsons, and from the movies Soapdish and Groundhog Day plus, of course, that shot of Alex Karras decking a horse in Blazing Saddles.
Oddly, the snippets which cost some $100,000 to use are uncredited. Explains director Randall Miller, ''Everybody got the same sort of agreement: If nobody got credit, nobody had to get credit.'' Seems that some people will go to any lengths for a hit.
