Rob is a multi-talented performance artist who gained international recognition as a musical artist and was then cast as AC/DC's late vocalist, Bon Scott, in the biopic, "Bon Scott - The Legend of AC/DC" which he also wrote. He was also considered as a strong candidate to replace current AC/DC vocalist, Brian Johnson, in 2016 due to a hearing issue Johnson has since overcome with medical treatment. News of Liotti's casting in the NBC Universal biopic went worldwide garnering considerable press for the actor.

 After the AC/DC biopic was shelved by NBC as a result of internal conflict with their music division, Rob went on to write, direct, and star in a crime drama he wrote called, "Family Values: The Rise of Anthony Morelli," a low-budget series pilot that was picked up and broadcast for international distribution. The initial installment of the "Family Values" franchise served as a useful proof-of-concept for the current limited series, "Family Values: The Corruption". The four one-hour episode limited series was greenlit in 2021, but was dropped from the slate with other projects after the global production company unexpectedly filed for reorganizational bankruptcy. It is currently out for funding and seeking its second green light. Notable name talent and some strong breakout artists are already attached to the project, and the project lost notable actors, James Caan and Tom Sizemore most recently to their untimely passings. 

 The writer also has a thriller in development called, "Zero Turn."
