Diamonds are forever
When you put in 60 years on the job, you might get a gold watch. When the queen does it, she gets a worldwide party. "The Diamond Queen" (7 p.m. Sunday, BBC America), a three-hour documentary, examines Queen Elizabeth's legacy, mainly through interviews with leading politicians and family members.
The alt awards
Jon Hamm ("Bridesmaids") takes on Jennifer Aniston ("Horrible Bosses") for the title of best on-screen dirtbag during "The 2012 MTV Movie Awards" (8 p.m. Sunday, MTV), hosted by Russell Brand. Expect "Bridesmaids" to get all the love it didn't receive during the Academy Awards.
How the West was won
"Longmire" (9 p.m. Sunday, A&E) is a crackling good contemporary western about a sheriff who carries a big stick -- and a big heart. If this new series does as well as History Channel's "Hatfields & McCoys," the most watched non-sports event ever on an ad-supported cable station, expect the TV landscape to start getting packed with dusty dramas. For an interview with Eden Prairie's Adam Bartley, who is in the cast, check out Sunday's Variety section.
