If you don't know Randi, he's a sucessful magician who had a second career debunking phoney psychics and other charlatans, after retiring from magic.
Randi is a charismatic and very compelling character. This documentary traces his long career and his personal life that includes touching on his coming out at age 84 and marrying his partner just recently in Washington DC. The film focuses on Randi's feuds with the spoon bender Uri Geller and the TV evangelist Peter Popoff. Both feuds resulted in humiliation and public debunking but Popoff and Geller somehow still have careers pedalling their snake oil. The film also pokes holes in the concept of the "real" and even turns the lens on itself as a documentary--that is, with a bias and constructed.
This is a fascinating, chock-full of fun, fun, schadenfreude-soaked totallu enjoyable doc. I highly recommend An Honest Liar.
5/5
