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.
