How I Met Your Dad is happening!

It’s official! A spin-off to How I Met Your Mother will be hitting a TV screen near you soon.

Indie film starlet, Greta Gerwig is set to star as Sally, a character described by producers as: “a female Peter Pan who has never grown up and has no idea where she’s going in life.”

The actress will also produce and co-write the show, which apparently will have a style more similar to HBO’s Girls than How I Met Your Mother. 

It is thought Sally will play a character similar to Ted Mosby, explaining to her kids how she met their father. However she will also be going through a divorce from a year long marriage at the time.

All we want to know is who is going to play the Barney character!
