here is a list of faceclaims i've seen used many times in tmr fanfictions!
DISCLAIMER: of course, if you feel like one of these actors/actresses fits your character, you can still use them. but if you're trying to make your story unique, i'd stray away from these people
LILY COLLINS
idk if this is a universal thing across all fandoms or what, but i've seen SO MANY PEOPLE use lily as a faceclaim in almost every fandom i'm in, including TMR
CRYSTAL REED
*points furiously at myself* MEEE! ME ME ME I HAVE USED HER but same with lily— she is pretty overused in multiple fandoms
MARIE AVGEROPOULOS
at first i was surprised to see marie because the 100 isn't *that* well-known, but now i see her all the time, mostly in thomas fanfictions.
HOLLAND RODEN
there is a 90% chance that this is a stydia fan having her be with thomas or making a stydia au out of tmr. i also see her a lot in multiple fandoms
EMMA WATSON
emma is less likely because she doesn't really have the ~*Teenager*~ look anymore, nor are there many suitable gifs (which most people cast their faceclaims for) but i've still seen her in many
CARA DELEVINGNE
this actually surprised me because models usually aren't used very much, but loRDY was i in for a wake-up call. cara is actually used quite a bit
ZOEY DEUTCH
i saved zoey for last because i actually thought this was kinda funny. i searched through the tag "the maze runner" and found about four fanfics right off the bat with her as the faceclaim, but they ALL USED THIS EXACT PICTURE:
which is honestly hilarious to me because it's from 2011 (so not at all recent) and it doesn't even show up when you search "zoey deutch photoshoot." i had to dig for this to prove a point.
