The Oxford-born performer, who portrayed Professor Sprout across multiple entries in the film franchise based on J.K.

Rowling’s wizarding novels, made the disclosure during a recent interview.

Margolyes has built a distinguished career as a character performer spanning cinema, broadcast television, and theatrical productions.

Her work earned her the BAFTA Award for Best Supporting Actress for her portrayal of Mrs Mingott in Martin Scorsese’s 1993 drama The Age of Innocence.

Beyond her dramatic roles, she has appeared on numerous talk programmes, where she developed a reputation for delivering straightforward responses to questioning.

The 85-year-old performer indicated in the interview that she is currently declining participation in certain television formats.

She disclosed that she had received inquiries regarding Celebrity Traitors, a programme her fellow performer Stephen Fry attempted to convince her to join.

She indicated that she considered the invitation due to her positive regard for Fry.

Ultimately, she concluded she could not commit to participation in such a programme.

Margolyes stated her aversion to formats requiring contestants to determine the inclusion or exclusion of other participants.

She expressed her disinclination toward competitive programmes generally.

The performer noted that substantial financial sums had been proposed for her involvement in both the Australian jungle-based programme and the BBC dancing competition.
