Chadwick played the role until 2010 when the decision was made to recast Amy to tie in with the return of her onscreen mother Tracy. The casting of seven-year-old Elle Mulvaney was announced in March 2010. A spokeswoman said "Amy has some big storylines coming up so we decided to recast an older child who could play younger. This is common practice. For example, Alex Bain is two years older than Simon is on screen." Mulvaney first appeared onscreen in May 2010.
