Daniel Frederick Wallace is a British filmmaker, comedian, writer, actor, and presenter of radio and television. His notable works include the books Join Me, Yes Man, and the TV series How to Start Your Own Country. As an author, Wallaces bestselling books have been translated into more than a dozen languages.

He began writing reviews for video game magazines at the age of 13 for school work experience: a reviewer had become ill and so Wallace was given the opportunity to review a game. At 18 he started writing comedy, mainly through the magazine Comedy Review. He specialised in radio production at the University of Westminster.

At 22, he became a BBC producer. He was part of the production team behind British Comedy Award-winning Dead Ringers, the original producer of the critically acclaimed cult hit The Mighty Boosh, and the creator and producer of Ross Noble Goes Global. As a journalist, Wallace has worked for The Scotsman, The Guardian, The Independent, Elle, Cosmo, The Times and other publications.

In 1999, Wallace challenged comedian Dave Gorman, who at the time was his flatmate, to find 54 other people called Dave Gorman (one for every card in the deck, including the Jokers). Wallace accompanied Gorman on his quest and the men created Are You Dave Gorman?, an award-winning comedy stage show about what happened during their journey. A BBC series, also co-written and co-produced by Wallace, followed, as did a book, written by both men.

In 2003, Wallaces book Join Me was published. The book explains how he accidentally started a cult called Join Me. The movement would go global, with each member committing to undertaking one random act of kindness for a stranger every Friday (Good Fridays). Tens of thousands joined. Join Me celebrates Karmageddon 10 in December 2011. Traditionally, hundreds of members travel to London for the meet-up and undertake good deeds for strangers, with Wallace present. The movement is now generally referred
