Since 2012 Jonny's had lead or supporting roles in eight Sundance premieres. Some of those recent credits include "Hellion" (the short) in 2012, "Pit Stop", "Black Metal", "Computer Chess" and "A Teacher" in 2013, with "Dig" & "Hellion" (U.S. Dramatic Comp) in 2014 and an appearance in David Lowery's "A Ghost Story" in 2017. His leading performance in "Good Night" (SXSW 2013) led SMELLS LIKE SCREEN SPIRIT to say "Jonny Mars is nothing less than a force of nature", & FILMMAKER MAGAZINE to write "[one] of the greatest dramatic performances in the history of Austin filmmaking." 2018 had Mars starring alongside BREAKING BAD'S Matt Jones in "A Bad Idea Gone Wrong", SONY PICTURES' recently acquired "Cover Versions" with Katie Cassidy, co-starring in Andrew Bujalski's latest, "Support the Girls", with Regina Hall and Haley Lu Richardson and as an antagonistic co-star in Season 2 of "Queen Sugar". Next, look for him in the Cannes's 2019 Competition film "Bacurau".
