'How I Met Your Father' Release Date, Cast, Trailer and Plot Details

A How I Met Your Mother spin-off series is in the works with the very simple but effective title How I Met Your Father.

It's exactly what you think it is—a sequel to the much-loved sitcom that ran for nine years on CBS.

Hillary Duff is leading the cast while This Is Us showrunners Isaac Aptaker and Elizabeth Berger are taking the helm.

How I Met Your Mother's original creators Carter Bays and Craig Thomas have signed on to executive produce.

"We are honored by their passion and vision, and look forward to helping them tell a legendary new story. Thanks to all the HIMYM fans out there who waited for it," Bays and Thomas said of revisiting the show in a new format, per Variety.

The series is set to air on Hulu with a 10-episode run and while no release date has been announced, it is expected to debut on the streaming platform in 2021.

In a statement to Entertainment Weekly, 20th Television president Karey Burke said of the show: "Our genius producers Isaac and Elizabeth who are—wait for it—legendary within our halls, have created a spectacular new take which both honors the original and is entirely their own."

Leading the cast as protagonist Sophie is Duff, who said she is "honored and nervous" to take on the role.

"I've been incredibly lucky in my career to play some wonderful characters and I'm looking forward to taking on the role of Sophie," Duff said per Variety.

"As a huge fan of How I Met Your Mother, I'm honored and even a little nervous that Carter and Craig would trust me with the sequel of their baby. Isaac and Elizabeth are brilliant, and I can't wait to work alongside them and all of their genius. Just fangirling over here getting to join the Hulu Originals and 20th families. I realize these are big shoes to fill and I'm excited to slip my 6 ½'s in there!"

Creators Aptaker and Berger said they "can't wait for audiences to meet Sophie and her crew, and watch them come into their own and find love in modern-day New York City." Adding: "And we hope nobody thinks it's weird that Bob Saget will be playing old Hilary Duff's voice.

Hulu's official synopsis for How I Met Your Father reads: "Sophie and her close-knit group of friends are in the midst of figuring out who they are, what they want out of life, and how to fall in love in the age of dating apps and limitless options." (per The Hollywood Reporter).
