Hilary Duff shares first BTS photo of the ‘How I Met Your Father’ cast

High fives for everyone because Hilary Duff is just as excited as fans are about Hulu’s upcoming How I Met Your Father series. That’s probably why she was quick to share one of the first behind-the-scenes photos of the cast from the set of the How I Met Your Mother adaptation, in which she stars.

“Who’s ready for us???,” Duff captioned the photo on Instagram. “We may or may not have been sitting in front of a certain someone’s apartment…. #himyf.”

That someone is clearly the unnamed, title father. However, in addition to Duff, the rest of the Legen… (wait for it)… dary cast is also all smiles, holding copies of their scripts. Many of them also shared the photo on their own social media pages, officially kicking off the fan frenzy.

On Wednesday, she shared a selfie on Instagram stories, writing "First day of school... ahem... work!!" Guess filming started today!

Duff was announced as the series lead, Sophie, in April. Two months later, Hulu revealed that Chris Lowell had been cast as the Uber-driving Jesse, an aspiring musician who is cynical about love. In mid-August, co-stars Francia Raisa, Suraj Sharma, Tien Tran, Tom Ainsley and Brandon Micheal Hall were also announced.

Sharma plays Sid, Jesse’s best friend and roommate who owns a bar that will inevitably be the gang’s new watering hole. Tran plays Jesse’s adoptive sister Ellen, who is also the most recent New York resident of the bunch, having just moved there from a farming town after breaking up with her wife.

Raisa stars as Sophie’s roommate and aspiring stylist, Valentina, and Ainsley plays Valentina’s new friend Charlie, who is the son of conservative aristocrats and comes from a major place of privilege. Hall plays Sophie’s Tinder match, Ian.

Much like the original 2005 series, in which Josh Radnor played a man telling his kids the story of how he met their mother, HIMYF revolves around Sophie telling her son the story of how she met his father. It takes place in present-day New York, where Sophie and her friends are navigating life and love.

Jason Segel, Cobie Smulders, Neil Patrick Harris, Alyson Hannigan and Bob Saget also starred in HIMYM, which ran for nine seasons and produced recurring gags like The Slap Bet, Barney’s Play Book and Robin Sparkles.

How I Met Your Father marks Duff’s first series since the end of Younger earlier this year. It’s also her first project since the Lizzie McGuire reboot was officially axed over creative differences. HIMYF is in production now, and Duff has already been giving interviews about the show and what ties it may have to the original.

"I don't want to give it all away and the script is definitely being changed a little bit. But it does tie in and, you know, hopefully, we'll have some fun guest appearances from the original cast,” Duff told Entertainment Weekly in May. "There's great characters and I'm going to get to have another on-set family, another TV family," she continued.

"There's so much opportunity for love stories with this show because it's Sophie and then, three dudes. So it's going down that whole rabbit hole of like, well, which one was the father? And you get to like go through all of Sophie's young experience of finding love and dating and what that's like in the modern world."
