This decision led him into quitting Paris 13 University where he attended communication studies to enroll in Alice Dona Studios, a performing arts school for future professionals in September 2000.

In 2004, Merwan enrolled in Elie Chouraqui and Maxime Le Forestier's musical entitled Spartacus in which he was cast as David's stand-in but he never had the occasion to portray the role.

[1] Soon after, Merwan was chosen to portray François, Duke of Beaufort in the musical Le Roi Soleil which opened for two seasons in Paris on 22 September 2005.

After the end of Le Roi Soleil, Merwan began touring France with his musicians to promote his future solo album due to release in 2012.

Merwan Rim's solo debut single, entitled "Vous" (meaning you in French), is available for legal download since 2 May 2011.
