Best of 2015: Top 20 Acting Performances

When I think back on the year's best acting performances in film, the first word that comes to mind is "surprise". Of the 20 performances I most anticipated at the start of the year, only 2 of them ended up on this final list. Instead, a slew of dynamic duos, breakout stars, comedians-gone-serious and A-listers at the top of their game came along and impressed me with their unforgettable turns. But most of all, 2015 was the year of the actress. Indeed, women dominated the top ranks of this Top 20, with a long line of other incredibly worthy performers just missing the cut. Compiling the following names was therefore as difficult as ever, but I'm happy with my choices. Here are the 20 performances that resonated with me the most in 2015:
Honorable Mention: Jason Mitchell in Straight Outta Compton
20. Greta Gerwig in Mistress AmericaA quintessential Greta Gerwig performance, at once insular and effervescent.
19. Kitana Kiki Rodriguez in TangerineThis raw, raucous performance snatched all the wigs.
18. Jesse Eisenberg in The End of the TourLike a slow jam on a Sunday afternoon, this subtle, generous performance found the right groove.
17. David Thewlis in AnomalisaA marvelous vocal performance as relatable and sympathetic as any I'd seen this year.
16. Jason Segel in The End of the TourWho knew he had this in him? - Pt 1
15. Seth Rogen in Steve JobsWho knew he had this in him? - Pt 2
14. Tom Hardy in The RevenantA brooding, brutish performance that fit Hardy like a glove.
13. Jessica Chastain in Crimson PeakA deliciously diabolical performance to die for.
12. John Cusack in Love and MercyA tortured performance conveying such pain and heartache, heart-rending from the very first scene.
11. Johnny Depp in Black MassThe year's most transformative, unnerving performance.
10. Leonardo DiCaprio in The RevenantThe epitome of "blood, sweat and tears".
9. Elisabeth Moss in Queen of EarthForget "The Walk", this fearless performance was the high-wire act of the year.
8. Oscar Isaac in Ex MachinaIt should be a crime to be so effortlessly cool.
7. Saoirse Ronan in BrooklynWith this absolutely luminous performance, Ronan confirmed herself as one of her generation's brightest stars.
6. Emory Cohen in BrooklynUtterly charming and sincere, a real "Mr. Right".
5. Amy Schumer in TrainwreckThis hilarious, surprisingly nuanced performance was far from a trainwreck. 
4. Lily James in CinderellaA genuine, sweet-natured gem of a performance of the kind that has long been under-appreciated in modern cinema.
3. Cate Blanchett in TruthIn the end, the real truth in this film was Cate Blanchett's tour de force acting.
2. Rebecca Hall in The GiftThe tremendous vulnerability and fragility on display here was like watching Mia Farrow in her prime.
1. Melissa McCarthy in SpyIf you want to know where all the movie stars have gone, look no further than Melissa McCarthy's strong, sweet, awkward, sexy, awesome work in "Spy".
