She was so glamorous, even as a little girl, that she got her first starring role in Hollywood by just walking into the studio. The fascinating Hollywood documentary “Elizabeth Taylor: The Lost Tapes” (HBO, 8 p.m.) tells the story of the glittering star in her own words during a late night interviewer in 1964 (with a Dominick Dunne interview later in her life covering the rest of her story).

Part of what she accomplishes is not only delineating her five marriages but explaining them — pushed into marriage by publicity agents as a teen; going for an older men after; with relationships ended by death. Well illustrated with crucial clips through her storied career, there are also a lot of shots of a reel to reel tape recorder spinning, but what she has to say is often compelling.

Autumn Reeder stars as a floundering woman who starts getting advice from an 8-year-old version of herself that suddenly starts to appear. The made-for-TV romance “Junebug” (Hallmark, 8 p.m.) also stars Aaron O’Connell. 

The other original film “I Thought My Husband’s Wife Was Dead” (Lifetime, 8 p.m.) involves an expectant mother who is interrupted by a ghost from her past. Sherilyn Allen, LeToya Luckett and Jamail Johnson star. 

When it comes to “Shark vs. Ross Edgley” (Nat Geo Wild, 9 p.m.), I’m betting on the fish. 

An abandoned house in California is investigated on “Ghost Adventures” (Travel, 10 p.m.).
