There are secrets and lies filling the month of May. Jaime Sommers must hide her very bionic being in Bionic Woman, the reimagining of the 70s Saturday teatime favourite in which a bartender gets the eye, ear, leg and arm of an Action Man, out on 12 May. Quinn Mallory finds out the truth about his family (and he's got his own secrets with the doorway to infinite parallel worlds hidden in his basement) in Sliders, season four, out on 19 May. The Cosby Show shows them all what life is like when you keep it all in the family – just one of the funniest and most photogenic in TV history, out on DVD with season one from 19 May.
