Which roles were perfectly cast?

[beguilingeyes]

To reverse the coin...

My absolute favourite bit of casting ever was Terri Garr as Phoebe's mum in Friends. She could absolutely have been her mother. Kathleen Turner as Chandler's dad (Helena Handbasket) was pretty good too.

Gerard Depardieu as Obelix in the Asterix movie :)

[Giggorata]

James Marsters as Spike in Buffy, perfection.

Olivia Coleman as Fleabag's wicked stepmother.

David Tennant and Michael Sheen as Crowley and Aziraphale in Good Omens.

Alan Rickman, as Snape in HP

Jim Parsons as Sheldon Cooper in The Big Bang Theory

Michael McManus as Kai in Lexx

Kyle McLachlan as Agent Cooper in Twin Peaks

Joanna Lumley as Patsy in AbFab

[JackPaul]

Yes to sam heughan, schitts creek and olivia coleman 😂

Marcia Cross as Bree in desperate housewives.

[ScorpioSphinxInACalicoDress]

David Tennant in anything.

Christopher Ecclestone in Dr Who.

Alison Steadman in Gavin & Stacey (though G&S should be on the other thread as it's a mystery how the eponymous main characters are such dreadful actors)

All the cast of Merlin except Angel Coulby. Merlin and Arthur both perfect.

In Harry Potter- Helena BC, Neville and Draco, Prof Mc.

Maggie Smith in Downton.

Glenn Close wasn’t in The Devil Wears Prada, though — do you mean Meryl Streep?

The passing years have taught us a lot more about Kevin Spacey but he is absolutely pitch perfect in American Beauty. As is Annette Bening.
