Daniel Frederick Wallace (born 16 November 1976) is a British filmmaker, comedian, writer, actor, and presenter of radio and television.

As a journalist, Wallace has worked for The Scotsman, The Guardian, The Independent, Elle, Cosmo, The Times and other publications.

Traditionally, hundreds of members travel to London for the meet-up and undertake good deeds for strangers, with Wallace present.

While on a book tour through America, Wallace was dubbed a "Generation X legend" by the Wisconsin State Journal.

[4] Wallace next wrote a short book called Random Acts of Kindness: 365 Ways To Make the World A Better Place, with the help of submissions from Joinees.

It includes many humorous Random Acts of Kindness (RAoK) ideas, such as "Contradict Demeaning Graffiti", and "Make An Old Man Very Happy."

[5] A film adaptation of Yes Man was developed with Warner Bros. and stars Jim Carrey and Zooey Deschanel.

[6] Wallace appeared on screen in a cameo in a bar scene in the last ten minutes of the film, holding a British pint glass.

It tells the story of Wallace's trip to Idaho, to visit a manhole cover in a small town, whose residents have proclaimed it the centre of the universe.

Wallace's book Awkward Situations for Men, was released on 3 June 2010 and reached number 3 in the best-sellers list.

Written by Wallace, this children's book series follows the adventures of ten-year-old Hamish Ellerby as he faces off against terrifying monsters, with the help of his best friend Alice and the other members of the PDF (Pause Defence Force).

[12] Wallace's 2024 book Somebody Told Me... investigates conspiracy theories and disinformation, and covers his meeting with Alex Jones.

In it, Wallace plays himself ("Danny"), a writer who moves to San Francisco to support his wife's new job, and finds that he doesn't quite fit in.

From 9 February 2008 to October 2008 Wallace presented a weekly show at 10 am – 2 pm on Saturday mornings at XFM London (now Radio X),[19] taking over the old Ricky Gervais slot.

On 1 August 2011, Wallace returned to XFM London to present the weekday breakfast show.

Wallace eventually used terminology such as 'listenerpad' and 'listening partner', to imply and joke about state-like rules for joining in with the show.

Similar idiosyncrasies to previous incarnations of the show are employed, while new features include: Wallace lent his face and voice to the 2009 video game sequel Assassin's Creed II where he played Shaun Hastings – an historian and modern day member of the Assassin Order.

In 2015, he voiced Alan in the indie game Volume, his second collaboration with Thomas Was Alone creator Mike Bithell.

He appeared in Channel 4's The IT Crowd (Series 1 Episode 2) in a role his friend, writer and director Graham Linehan, originally planned to play himself.

[22] Wallace was the first person in 43 years to be asked to front an episode of flagship BBC science series Horizon.

[24] He appeared on Friday Night with Jonathan Ross on 20 June 2008 to discuss his books, film and television projects.

In October 2012, American television network ABC added a comedy project to be co-produced by Wallace entitled Man & Boy.
