Alexis Dubus (born 1979) is an English alternative comedian and actor known for his French alter ego Marcel Lucont.

Born in Buckinghamshire, he studied Philosophy and Psychology at the University of Warwick, where he became part of the sketch troupe Ubersausage.

In 2003 he set up Falling Down With Laughter Comedy Club in London Bridge with fellow comedian Sy Thomas.

He returned to perform in the 2018 Fringe, praising a new initiative which helped to put more money in the artists' pockets by dropping inside ticket charges, but left disappointed that the festival was still not suited to independent producers and venues, losing track of the reason for its initial inception.

[8][9][10] Dubus hosts the Comedy Cul-de-Sac podcast, in which established comedians give accounts of their worst ever experiences on stage.
