Marcel later recalled that during filming the show's dream sequences, she often had to dress up in "awful" outfits such as a cat suit donning Barbarella and a Union Jack Flag.
[2] Prior to this, she appeared in over twenty episodes of The Bill, in which her character, Louise Larson had an affair with Sergeant Dale Smith.

The doctors told me I'd almost bled to death and further tests revealed I had a blood clotting problem, the female form of haemophilia.
The disease left her almost bed-bound for two years until she was seen by an immunologist at St Bartholomew's Hospital in London, who diagnosed the condition and put her on immuno-suppressants.
[20] In August 2014 Rosie announced her pregnancy, which they found out about two days before starting IVF treatment following months of trying to conceive and suffering a miscarriage.
Due to Marcel's rare clotting disorder (known as storage pool disease), the baby, called Beau, was born via caesarian section.
