Ellen Gray's weekend TV picks
This week, she features "Masters of Sex," "Homeland," all things Mandela and "Psych: The Musical."
* MASTERS OF SEX. 10 p.m. Sunday, Showtime.
One of the best shows of 2013 wraps up its first season with an episode I certainly hope reunites estranged researchers William Masters (Michael Sheen) and Virginia Johnson so they can (eventually) tell America all the things they learned about sex during those late nights they worked together.
* HOMELAND. 9 p.m. Sunday, Showtime.
Maybe it's hard to take the saga of Carrie Mathison and Nicholas Brody as seriously as we once did - USA Network's "Covert Affairs" might be at least as realistic a portrait of the CIA - but the action has heated up in recent weeks and it's still possible this season can be saved at the very last minute. Right?
* MANDELA, MANDELA AND DE KLERK and AMANDLA! A REVOLUTION IN FOUR PART HARMONY. Noon, 2 p.m. and 4 p.m. Saturday, Starz and Encore.
Starz and Encore mark the passing of Nelson Mandela with a simulcast of two documentaries and a 1997 bio-pic, "Mandela and de Klerk," starring Sidney Poitier and Michael Caine.
* PSYCH: THE MUSICAL. 9 p.m. Sunday, USA.
The hills around Santa Barbara are alive as USA's longest-running original series, about a fake psychic detective, unveils a two-hour musical episode that has a few advantages over NBC's "Sound of Music Live": It's not live, it's not a remake of a beloved classic and it's not just a musical - it's a crime-solving musical. Who could resist?
