Rosie is a bilingual comedy writer and actor who grew up in the English countryside and found her second home in Rome. On the comedy circuit she is known as Marta Loren, Sophia Loren’s fictional and very jealous sister. Marta was born out of Rosie’s love for improv and character comedy, and she has performed at several famous London venues including MOTH Club and The Groucho Club. Rosie trained at The Free Association and has been part of the all-female improv team Slumber Party for four years, appearing at festivals such as Boom Chicago, Prague Fringe and The Edinburgh International Improv Festival. She is co-founder of sketch platform Orca Comedy and shortlisted for the Funny Women Comedy Shorts Awards 2025. Rosie is currently developing a comedy TV pilot Maiden Italy based on her time working for a dysfunctional advertising agency in Rome. She will graduate from the NFTS’ Writing and Producing Comedy diploma in 2026 and go on to apply her sketch and sitcom skills in writers rooms.
