Must-watch: Eddie Redmayne singing 'Memories' as a child.

While making an appearance on The Late Late Show With James Corden to promote his new film ‘Fantastic Beasts and Where To Find Them’, Eddie Redmayne reminisced with Corden about their early acting days.

Eddie spoke about how he used to sing ‘Memories’ (from ‘Cats’), and in classic Corden fashion he decided to share the video evidence with the audience - and it is potentially the most adorable thing you’ll watch all day.

They also performed a skit of Redmayne attempting to go through airport security, with Corden as the TSA agent inspecting his suitcase.
