I wouldn't say all these films are about "what it is like to be misunderstood or scrutinized." However, if I were to pick my two favorite performances out of this list of films, they'd probably be:
Gary Oldman as Joe Orton in Prick Up Your Ears:
Oldman is playful, cheeky, full of life and, yet, a little sad behind it all.
Ian McKellen as James Whale in Gods & Monsters
Still McKellen's best screen role. He is absolutely captivating here in this largely imagined take on director James Whale's final few days.
