The first of many members of the "Sex Education" cast to appear in "Barbie", Emma Mackey is best known for her role as Maeve Wiley on the hit Netflix comedy. Since breaking out in that role, she has gone on to lead a number of films including "Emily", exploring the life of "Wuthering Heights" author Emily Brontë. She also starred in Kenneth Branagh's adaptation of the classic Agatha Christie novel, "Death on the Nile". She scored herself more recognition from BAFTA when she won the Rising Star Award this year.
Her character in "Barbie" has been described as a physicist Barbie with a Nobel Prize. Given that she has often been likened to Margot Robbie, it'll be interesting to see the pair on screen together.
