Main article: Tim Heidecker
Tim Heidecker is the creator and primary host of On Cinema, having hosted the original podcast, most of On Cinema at the Cinema, On Cinema and More! in the Morning, and On Cinema On Demand. He is also the creator of the hit spy series Decker, the founder and former front-man of the hit band Dekkar, the CEO of HEI Inc., and the founder of HEI Network.
Tim is known to prioritize his own personal issues on the show over movies, including talking about his various health issues, relationship issues, political stances, and music career. He is a staunch conservative and has discussed being pro-life, anti-vaxx, and anti-immigration in the past. He also endorsed Donald Trump in 2016. He has involved himself in alternative medicine frequently, such as Dr. San's acupuncture, Dr. San's nutritional vape system, Rio-Genesis, RJ's Shake, and Grain Water, which often had negative effects. Dr. San's vape system, in particular, led to both the burning down of Gregg's Victorville Film Archive and the death of 19 civilians at Tim's Electric Sun Desert Music Festival, which led to a contentious court trial where a mistrial was eventually declared.
Tim has had four ex-wives. The first, Stephanie, was never seen and divorced him in 2013. The second, Ayaka Ohwaki, he dated from 2013 onward, I got bored finish this soon
