Martin Freeman is much-loved as the star of BBC TV series The Responder, where he plays Chris Carson, an urgent response officer on the beat in Liverpool. His co-stars in the gritty drama include Adelayo Adedayo as Rachel and MyAnna Buring as Chris' wife Kate Carson – plus viewers will recognise Josh Finan as Marco from his role in Netflix's smash hit Baby Reindeer. But Martin reportedly hasn't always got along with all his co-stars.
