Tom Hanks has broken his silence on his daughter's new bombshell memoir detailing her troubled childhood.

The actor, 68, opened up about the book, The 10: A Memoir of Family and the Open Road, written by his only daughter E.A. Hanks, during a red carpet premiere for his new film 'The Phoenician Scheme' on Thursday.

Hanks praised her for being so candid about a dark time in her life and also noted he was not at all shocked that she had the strength to do so.

'I'm not surprised that my daughter had the wherewithal as well as the curiosity... in order to examine this thing that I think she was incredibly honest about,' the Toy Story star told Access Hollywood.

He went on to say that his daughter has been 'very open about what the process is' in regard to the book.
