- The Danza: She plays a girl called Kate in Dates.
- Dye Hard: She's naturally blonde but is brunette in most of her roles, except Dracula. She had to dye it brown for Merlin initially, overlapping with Dyeing for Your Art.
- Fake American: As Jules Daly in A Princess For Christmas, Gloria Miller in The Throwaways, Sarah Bennet in Slasher and Lena Luthor in Supergirl (2015).
- Fake Brit:
- Name's the Same: This particular Katie McGrath is not married to J. J. Abrams.
- Ooh, Me Accent's Slipping: It's not really noticeable unless the viewer themselves is British or Irish, but that minor Irish twang frequently rears its head whenever she's trying to adopt a foreign (read: American) accent. She's pretty good at sticking to RP, though.
- Playing Against Type:
- Playing with Character Type: She inverts her role on Merlin in Supergirl (2015). In the former she was the evil scheming sister of a benevolent prince, trying to seize power from him. In the latter she's the sister of a notorious villain and inherits his empire naturally, trying to prove to everyone that she is not the villain.
- Promoted Fanboy:
- Initially as a history nerd to roles in period dramas, especially since DVD bonuses reveal her favourite character of the legend of Arthur is Morgan le Fey.
- Superhero nerd to recurring role as Supergirl's best friend.
- Star-Making Role: Needless to say, Merlin gave her some very immediate success as an actress and she's been working steadily ever since. Her character Zara in Jurassic World is a massive Ensemble Dark Horse, leading to a new level of attention for her as well.
- In the US, it's probably as Lena in Supergirl (2015).
- Those Two Actors:
- Typecasting: Usually as an aloof, often evil, upper class lady in period pieces. Overlaps with Cast the Expert since she studied history at Trinity College - the most prestigious university in Ireland."I guess I'm just more realistic in a corset and funny hairstyles."
- What Could Have Been: She almost didn't get the part of Morgana due to her Irish accent. Word of God is that with Colin Morgan being cast as Merlin, they didn't want two Irish characters on the show. Had Colin not been able to be a Fake Brit, Katie herself would have been required to do the accent - and if she hadn't, they wouldn't have cast her.
