This is the brilliance of the film - those speeches were so powerful and utterly believable... but you wanna know something? MLK didn't say any of those things. Steven Spielberg owns the movie rights to MLK's speeches, so the writers of Selma had to study the composition of his speeches and craft convincing ones from scratch.
I've heard a lot of people praise the speeches but it's the writer's responsibility, not MLKs.
Exceptional writing combined with Oyelowo's terrific performance = a great on-screen depiction of MLK. I also really appreciated the movie's efforts to display his more human side. We usually think of him as a moral crusader, a speaker, a peaceful activist. But he was also a strategist and a pragmatist, as shown in the film.
I don't know why people are complaining about Johnson. I don't know anything about the man irl but in the film he clearly agrees with MLK in terms of ideology, from beginning to end.
Great performances by Wilkinson and Tim Roth too, but I really disliked the sheer number of cast members. Very few of the supporting characters had any real relevance, and they were almost all very underdeveloped. Speaking of which, it would be hard to argue that this really explored MLK's life, because it didn't. I don't know if I was expecting it to be more of a biopic than it was - maybe I was just expecting something else.
Bradford Young shot the movie beautifully, with a light mix of browns and reds (symbolising racism and blood?) plastered crisply across the film.
That being said - the film doesn't actually feel very special. Remove David Oyelowo from the picture and you have a fairly standard, generic, solid film about activism. There were plenty of powerful moments but it felt almost childlike in its blatant attempts to make you feel guilty and sympathetic. Either way, I did cry a little at the end, when Lyndon B. Johnson was giving his speech.
Overall a decent but not amazing film, with some truly impressive accomplishments but not much else.
7/10 - B
