Don’t go looking for laughs in the screen biography “Gleason” (8 p.m. Sunday, CBS), starring Brad Garrett as the Great One. Garrett, who just won an Emmy for his role as Raymond’s sad-sack brother Robert on “Everybody Loves Raymond,” does a remarkable job here, capturing Jackie Gleason’s volcanic comic energy as well as his brooding, nasty, chain-smoking and alcoholic off-stage personality.

“Gleason” may not be the feel-good movie of the year, but viewers owe it to themselves to catch Garrett’s memorable and career-making performance. Move over Raymond, a star is born.

“Bang Bang You’re Dead” (7 p.m. Sunday, Showtime) takes an unflinching look at high school cliques and social cruelty and the violence they inspire. Tom Cavanagh stars as Val Duncan, a concerned drama teacher who believes that he can engage his school’s most volatile student, Trevor (Ben Foster), by casting him in a one-act play about a Columbine-like school shooting.

For all of its gritty realism, the film’s precocious teens are simply too self-aware and articulate to be believed. Cavanagh, who plays a naive romantic on “Ed,” plays an idealistic romantic here. Look for Janel Moloney (“West Wing”) as his more down-to-earth faculty colleague.

“Brady Bunch” star Maureen McCormick takes a polyester time trip on “That ’70s Home” (8 p.m. Sunday, HGTV), an affectionate look back at the curious furniture, fads and decor choices of the decade when almost every refrigerator seemed to come in one of two colors: harvest gold or avocado. More than mere nostalgia, “Home” looks at some of the 1970s artifacts that have become expensive collectibles and even museum pieces.
