Marcy began her African television career in 2010, after a very successful acting career in the U.K as the lead on the Mnet show '53 Extra'. From there she was nominated amongst hundreds of contestants as one of the two chosen co-hosts on Africa’s number one talk show “Moments with Mo” which is exclusive to EbonyLife TV; Africa’s premium entertainment channel.

In terms of acting, one of her most memorable roles was in the play 'Iya-Ile’ (The First wife), produced by Soho Theatre/the Tiata Fahodzi Company in the UK.

This play was nominated for the Most Prestigious British theatre awards, The Lawrence Olivier Award in the "Outstanding Achievement in an Affiliate Theatre" category.

Marcy was also cast in the BBC mini-series 'Vexed' where she played the character of Tina T,  one of three members of a pop band and the heart and soul of the group. She then segued into the African industry because of her deep love for homegrown entertainment.
