Lionsgate, the movie and television company, is soon expected to join the growing ranks of production houses that have signed independent deals with the Writers Guild of America.

A deal is expected in the next day or so, according to people who have been briefed on the matter but requested anonymity because they weren’t authorized to speak. Lionsgate produces Showtime’s “Weeds” and distributes AMC’s “Mad Men.”

The Weinstein Co. and United Artists are among those that have already signed independent deals. The agreements are designed to be superseded by any deal ultimately reached between the striking writers and the Alliance of Motion Picture and Television Producers.
