Showtime Lets Comedian Gary Owen Do What He Does Best in #DoinWhatIDo

Tonight's TV offerings really run the gamut. From stand-up specials, to historical epics, to relationship shows, to an identity-stealing woman determined to turn back the clock, there's a little bit of everything to keep you entertained. Here are the highlights.

COMEDY SPECIAL: Comedy specials are hot these days, and Showtime's latest offering, Gary Owen: #DoinWhatIDo, looks like a great pick for some Saturday night laughs. This is the comedian's fourth special for Showtime, and he uses his appearance at the Charline McCombs Empire Theatre in San Antonio to shares tales from his personal life, offer his take on celebrity scandals, and touch upon sensitive race issues, all while keeping the laughs coming. Watch the preview. 10:30 PM ET on Showtime

CABLE PREMIERE: HBO's big Saturday night movie this week is Mary Queen of Scots. Based on the book by John Guy, the film brings a feminist perspective to the historical tale of Mary Stuart (Saoirse Ronan) who returned to Scotland in 1561 to reclaim the throne from England's Queen Elizabeth I (Margot Robbie). Watch the trailer. 8:00 PM ET on HBO

SEASON PREMIERE: The second season of Love & Marriage: Huntsville brings back the popular real life couples viewers have grown to love, and if the preview for the upcoming season is any indicator, the drama has only grown, with escalating fights, accusations of infidelity, and a baby on the way. 9:00 PM ET on OWN

MADE FOR TV MOVIE: Lifetime continues plumbing the depths of cheerleader-centric high drama with Identity Theft of a Cheerleader. The film follows Vicky (The Last Ship's Maiara Walsh), a despairing 31-year old woman, who believes her life went off the rails when she dropped out of high school in her senior year. Determined to give herself a reset, Vicky decides to "steal" a teenager's identity and re-do the senior year that never was. 8:00 PM ET on Lifetime
