Business Notes TAKEOVERS

Would J.R. Ewing submit quietly to being taken over? No way, but the ( financially troubled TV studio that created him, Lorimar-Telepictures, may soon accept that fate. Lorimar, which produces Dallas and Knots Landing, has stumbled badly after expanding too fast into areas beyond its ken, including feature films (among its flops: Made in Heaven and American Anthem). Last week the company agreed to a friendly acquisition by Warner Communications, whose TV studio already produces such hits as Night Court and Growing Pains, for $630 million in stock and the assumption of $550 million of Lorimar's debt. But late in the week came word of a potential rival bid. Marvin Davis, the Denver oilman who once owned 20th Century Fox, is considering making an offer of about $690 million for Lorimar. A Dallas-style brawl may ensue.
