Teller, born Raymond Joseph Teller, is a multitalented American personality who has thrived in etching his name in showbiz as a magician, actor, director, writer and painter and is perhaps best known as the non-speaking half of the famous American comedy magic duo Penn & Teller. Teller formed the illusionist duo Penn & Teller along with Penn Jillette in 1975 and over the years they have earned repute as distinguished magicians, entertainers, and scientific skeptics with their remarkable performances that include elements of both comedy and magic. While Penn serves as orator and raconteur of the act, Teller normally refrains from speaking during performances, and instead communicates through mime and nonverbal expressions. Teller has featured in several stage and television shows including in Penn & Teller: Fool Us and Penn & Teller: Bullshit!; and co-wrote three magic books with Penn. The two are presently headlining at the Rio hotel and casino in Las Vegas where they are performing since 2001, emerging as the longest running headliners to entertain at the same hotel in the history of Las Vegas. Teller is a H. L. Mencken research fellow at the Cato Institute as Penn. They are also staunch atheists and advocates for scientific skepticism and libertarianism. Other endeavours of Teller includes authoring the book When I'm Dead All This Will Be Yours!: Joe Teller – A Portrait by His Kid; directing the feature film documentary, Tim's Vermeer; and co-directing a version of Macbeth and a version of The Tempest.
