Dan Stevens' daughter helped design Emma Watson's flowing yellow dress in 'Beauty and the Beast'

Speaking about the movie and his child's input on 'This Morning' on Friday (17.03.17), the British hunk - who also has four-year-old son Aubrey with his wife Susie Hariet - said: "She [Willow] was five when we made this film. During the filming and the process of developing the film and they were working on the dress - what style, what colour. During that time Emma Watson came over to our house for dinner. We were talking about the dress and the dress design and Willow who was five at the time overheard the conversation. And we were talking away and she nipped off next door with a pen and paper. She came back half an hour later with five different dress designs. She sat down with Emma and talked her through the dress designs and Emma was so sweet with her as they discussed the different merits of the different dresses and they picked one."

And his oldest child was over the moon when she saw Emma adorn her design when she was filming the ballroom dancing scene with her father.

Dan said: "A few weeks later Willow comes on set to see the ballroom scene when we are dancing and daddy is in his hippo suit and Emma is in the dress, she just looked at me 'That's the one.'"

However, Dan's costume was not as glamorous as his colleagues, as he had to wear a "muscle suit" made of grey Lycra, which weighed 40 lbs and had to walk on stilts whilst shooting scenes for the highly-anticipated romantic movie.

He explained: "They created this [the Beast] out of two different kinds of CGI technology fused together - never been done before.

"So I was puppeteering a muscle suit on set, covered in grey Lycra on 10-inch stilts, so all the body happens on set.

"[It weighed] about 40 lbs. It was very heavy and hot and awkward.

"The facial capture is done separately, so every week I'd go in a booth and they'd spray my face with UV dots and I'd do everything we had done the previous week, whether it was eating, sleeping, roaring, waltzing, just do it again with my face. It blows my mind, it makes my child inside very very excited. Because it is a totally futuristic idea fused with a classic fairy tale."
