Alan Rickman, David Thewlis, Gary Oldman and all those are iconic in their roles in Harry Potter, but I’ll always be a bit sad about that casting, because having that ‘Marauders era’ cast be age appropriate would’ve just been so much better for the story.
Sirius wasn’t this old man who spent 12 years in Azkaban, no he got locked up at 21. He spent almost third of his life in a cell. He wasn’t this wise father figure to Harry, he was a reckless thirty-something who never really got the chance to mature past 21.
Remus was an exhausted, bone deep tired man carrying both physical and mental scars from the suffering he went through. Because he’s a werewolf, because of the war, because he lost all of his friends. And he’s only 33 when first introduced.
And Snape. Snape wasn’t an old bitter man who just hated everyone and enjoyed being antagonistic. He was 31 in Harry’s first year. He began to work for Voldemort as a teen, and as a double agent at 20. He’s a thirty-something bitter man, who never got to really live or make real connections. From Harry’s perspective he’s scary and intimidating, but really he’s just kinda…sad and pathetic. And then especially that scene where Snape is begging Dumbledore to help save Lily, and promising anything in return. (Because apparently Dumbledore needs something in return…for saving people.) He’s twenty. Barely out of his teens. Rickman was good in that scene, but having someone who actually looks twenty, would better show how scared, young, guilty and just desperate he was. That might not put Dumbledore in such a good light, though.
And then, the characters I think would’ve been the most important to cast age appropriately. And most people probably already agree and know who I’m talking about. James and Lily. They were 21 when they died. When Harry sees them in the mirror of Erised, they’re 10 years older than him. That’s the age difference Ron has with Bill. In that scene I might understand somewhat them being in their thirties, because that’s what Harry wants. He wants his life with his parents, he wants to have been raised by them. Though, I don’t know if the mirror could know what they might’ve looked like in their thirties, since they didn’t live that long. But then, in the cemetery when Voldemort’s wand spits the last spells cast, we see Lily and James as they were. 21. They’re telling their son to hold on just a moment longer. And they are 7 years older than him. In Deathly Hallows, Harry sees Voldemort kill them. They’re not this happy couple who’s got to love each other for a long time, only to have that happiness torn from them, no they started at Hogwarts ten years ago. They’re 21, and they’ve barely tasted that happiness. At the end of the book Harry talks to his parents. They comfort him and promise to stay with him, as he goes to die. Harry’s seventeen. James and Lily are four years older than him.
It wouldn’t have felt as nice. Harry being comforted by someone who looks almost his age. But it wasn’t nice. It was pretty tragic. Casting people who look 21, would’ve really made it land on the audience. It was a tragedy. They were barely adults.
