First look at How I Met Your Mother spin-off

We’ve been offered our first glimpse at How I Met Your Father, and it already looks legen – (wait for it) – dary.

Filming is officially under way on How I Met Your Mother spin-off, How I Met Your Father.

Series lead Hilary Duff has shared a photo on Instagram from the first day, along with the caption: “Hello, I’m Sophie.”

The official new Instagram page for HIMYF, which will air on Hulu, also offered a glimpse at the cast during filming.

The iconic original series, which starred Neil Patrick Harris, Cobie Smulders, Josh Radnor, Alyson Hannigan, Jason Segel and Bob Saget as the narrator, finished up after nine seasons in March 2014.

The spin-off was finally confirmed in April this year, following months of speculation.

The original series was a huge hit.

The show will follow Sophie (Duff) as she tells her son the very detailed story of how she met his father.

Like the original series, it will showcase the highs and lows of Sophie and her closest friends’ lives as they attempt to navigate relationships and search for true love.

Duff, who most recently starred in Stan’s hit Younger, is also serving as a producer.

“As a huge fan of How I Met Your Mother, I’m honoured and even a little nervous that [HIMYM creators] Carter and Craig would trust me with the sequel of their baby,” she told Deadline in April.

Duff’s castmates were announced earlier this year – and include Francia Raisa, Tom Ainsley, Tien Tran, Suraj Sharma, Chris Lowell and Josh Peck.

Daniel Augustin will play Sophie’s love interest.

According to The Hollywood Reporter, Hulu has ordered a 10-episode run of the spin-off, although an official premiere date is yet to be announced.
