It’s a mess at the Los Angeles Times right now. A plan to have Hollywood producer Brian Grazer guest-edit the Sunday Current section has gone awry — in part because editor Andres Martinez was having an affair with Grazer’s publicist, Kelly Mullens. Martinez has since resigned in protest through a post on the LAT Opinion blog because the Grazer-edited section, an ill-conceived and desperate idea if ever there was one, had been canceled. Nikki Finke has more. That such a plan was seriously considered, with L.A. Times publisher David Hiller apparently in the know about the Martinez-Mullens affair, is an astonishing conflict of interest. Oh well, at least Martinez had bitter words to say about the planned merger of the Opinion section and the LATBR. Even so, whatever Martinez’s talents or convictions, this is embarrassing for all parties.
