The veteran performer faced immediate criticism following the interaction, which unfolded during a live broadcast on the programme presented by ITV.
The exchange between Margolyes and the television presenter began with discussion about his manner of speaking before progressing to questions regarding his ethnic origins.
Peters was asked directly about his racial identity, to which he responded with apparent surprise.
Margolyes suggested he possessed mixed heritage, prompting an awkward confirmation from the presenter.
She subsequently made assumptions about his family background, inquiring whether he had a black father and white mother.
Peters clarified that both his parents were black, then appeared bewildered as he questioned whether his complexion differed from typical expectations.
Margolyes introduced the term high-yalla, explaining it described individuals of African descent whose colouring was not deeply dark.
Peters indicated he remained unaware such distinctions existed.
Margolyes insisted such categorisations were valid.
During the exchange, Peters appeared to receive guidance through his earpiece and noted that production staff were expressing concern.
Margolyes attempted to reassure those involved, stating that the programme welcomed people from all backgrounds.
She connected the discussion to a literary project she intended to pursue, indicating her desire to address similar themes in written work.
Margolyes described the conversation as concerning inclusion.
The segment rapidly gained attention across online platforms, generating sharply contrasting responses from internet users.
Detractors labelled the behaviour inappropriate and called for the performer’s removal from future broadcasts.
One social media commentator described the interaction as mortifying, while another expressed exhaustion with deliberate provocations that seemingly went unchallenged.
A further critic questioned the standards applied to individuals considered national figures.
Supporters of the discussion contended that examining racial heritage represented a legitimate topic for conversation.
Margolyes has developed a reputation for unscripted television moments, with her forthright remarks repeatedly attracting media coverage.
The performer portrayed Professor Sprout across the Harry Potter film series and has maintained an extensive professional presence in cinema, broadcast media, and stage productions spanning numerous years.
