Supermodel, in which the pair was nicknamed "Bronnie", the relationship on Survivor: Gabon between Charlie Herschel and Marcus Lehman, and American Idols Kris Allen and Adam Lambert, which was given the name "Kradam". Cultural references Film Buddy films have to a degree been rebranded as bromance films, although critics draw a distinction between the two, noting that a buddy film tends to be more explicitly violent and less open about its latent homosexual content. The intersection between buddy films and what would come to be called the bromance film was noted comedically at least as early as 1978, when National Lampoon ran a parody ad for the football-themed buddy film Semi-Tough, renamed "Semi-Sweet" and featuring an illustration of stars Burt Reynolds and Kris Kristofferson holding hands. Prominent examples of bromantic comedy include Judd Apatow's The 40-Year-Old Virgin (2005) and Knocked Up (2007), as well as Greg Mottola's Superbad (2007), which targeted non-sexual homosocial behavior and masculinity in inventive ways. Zoolander (2001), Wedding Crashers (2005), Funny People (2009), John Hamburg's I Love You Man (2009), The Hangover (2009), and Horrible Bosses (2011) are other examples. Although J. R. R. Tolkien's novels predate the "bromance era", the portrayal of the lifelong close relationships between Frodo Baggins and Samwise Gamgee, Meriadoc Brandybuck and Peregrin Took, and Gimli and Legolas in the novels have been characterized as bromance, as well as the depictions in the films based on them. The theme remains popular, with different genres looking at the concept in various ways, such as the documentary Best of Enemies – about the 1960s feud between intellectuals Gore Vidal and William F. Buckley. Television Bromance on television has also become more commonplace. It appeared early-on in the partnership of two CIA/KGB spies in the 1960s' Man from U.N.C.L.E., and in the 1970s' buddy-cop show Starsky & Hutch, which producer Aaron Spelling called "TV's first heterosexual love affair". Some critics also point to the 1970s' Odd Couple, about which executive producer Garry Marshall has said, "The network was concerned that we were being too gay." In October 2008, TV Guide placed Gregory House (Hugh Laurie) and James Wilson (Robert Sean Leonard) on the cover, under the headline "Isn't It Bromantic?". Brody Jenner, featured on MTV's reality show The Hills and the subject of bromance discussions for his relationships with castmates Justin Bobby and Spencer Pratt, debuted his own series on the network, called Bromance, on
