10 Great TV Shows Starring The How I Met Your Mother Cast
1. Buffy The Vampire Slayer - Alyson Hannigan
You won't find a more iconic or popular show starring a cast member from How I Met Your Mother than Buffy the Vampire Slayer, which cast Alyson Hannigan as the lovable Willow Rosenberg long before she became one-half of the most endearing couple on TV.
Buffy the Vampire Slayer is set in the fictional town of Sunnydale, where the titular vampire slayer (Sarah Michelle Gellar) is forced to face-off against numerous supernatural threats whilst battling the relatable horrors of high school and college life.
Gellar is joined by best friends Willow and Xander Harris (Nicholas Brendon), vampire lovers Angel (David Boreanaz) and Spike (James Marsters), and mentor Rupert Giles (Anthony Stewart Head), as the world continuously threatens to end and the world-saving gang are pushed to the breaking point at every turn.
As an added bonus, Hannigan met her husband and HIMYM co-star Alexis Denisof during the show's third season, and Denisof went on to become a main character on Buffy's masterful spin-off Angel. You love to see it.
