Actor Chiwetel Ejiofor has admitted that his Love Actually co-star Andrew Lincoln’s character in the film was a bit ‘problematic.’ In the 2003, Richard Curtis-directed Christmas romantic comedy, Lincoln played the charming Mark, who is obsessively in love with Juliet (Keira Knightley), the wife of his friend Peter, who was portrayed by Ejiofor. People have come to consider Mark’s character to be problematic, with some labelling his behaviour as that of a stalker and a creep.
