'Harry and Meghan: Becoming Royal' premieres on Lifetime

For Tiffany Smith, taking the role of Meghan Markle in Lifetime's "Harry and Meghan: Becoming Royal" wasn't to be done lightly. From watching "Suits" to studying YouTube and Instagram videos, she wanted to get Markle right, down to even her smaller gestures.

Smith picked up on a way Markle pushes back her hair and a way she speaks to her now-husband Prince Harry.

"When I was working on the sides for the callback, I was working with a friend and I'd done like the hair tuck and then there's also, she's just such a beautiful woman, but she does this thing where she looks up through her eyelashes and it's just, it's so sweet and beautiful and so I noticed that she does it especially a lot of times when she's talking to Harry. And so, I was doing it on the tape with my friend and he was like, 'Stop. That was so weird.' He's like, 'You are so much like her right now,'" she said.

The Lifetime film documents the royal couple's journey from dating through to the Royal Wedding.

"Harry and Meghan: Becoming Royal" premiered on Monday night local time.
