People magazine was the only entertainment-related magazine able to put Heath Ledger on its cover this week, since all of its rivals had already gone to press following his death. As a result, the magazine will have the advantage this week in the competition at the supermarket check-out lines over such competitors as Us Weekly, Star and OK. Us will feature Hannah Montana star Miley Cyrus; OK, Britney Spears; and Star, sister Jamie Lynn Spears. Meanwhile, the gossip website TMZ reported today (Thursday) that Jake Gyllenhaal, who costarred with Ledger in Brokeback Mountain and became close friends with him, is too upset to comment on his death. Gyllenhaal is currently filming Brothers in New Mexico, and, according to TMZ, "the set has been closed to non-crew members and extra security has been hired" to prevent reporters from approaching the actor.
