20/20: Mad About Oscar With Katie 10 p.m., Channel 5

In preparation for this Sunday’s Academy Awards, the newsmagazine goes all Oscar. Katie Couric hosts this clip and interview fest that will cover “the most memorable and moving acceptance speeches of all time” — expect to see Sacheen Littlefeather and Sally Field — funny monologue bits — we’re guessing anything involving Clooney — and a look at red carpet fashions through the years. Helping Couric dive into Academy history are former winners Field, Marisa Tomei, Denzel Washington, Cuba Gooding Jr., and Whoopi Goldberg as well as past hosts like Goldberg and Billy Crystal, and 2013 nominees Washington, Field, Bradley Cooper, and Jennifer Lawrence.
