Dominic West has revealed he was issued a stern warning by his own mother-in-law Olda before leaving to film The Pursuit Of Love with Lily James.
The married actor, 51, who sparked worldwide attention when he was pictured on a cosy weekend in Rome with his co-star, 32, admitted his wife Catherine Fitzgerald's mother told him he couldn't 'mess up' the part as she was a lifelong fan of the book.
Dominic, who plays Uncle Matthew in the BBC period drama - has since insisted he and his wife Catherine are still together despite his behaviour with Lily, but has reportedly agree to never speak to the actress again.

She wrote: 'My eldest daughter and my darling son-in-law who both work so hard to keep me in clover! How lucky am I? Hooray darlings congrats on sweet photo.'
