Roles that would seem different with age-appropriate actors?

Kate Bosworth is not a bad actress but yeah, not really a great Lois Lane in this movie. I remember seeing someone somewhere write that Parker Posey should have been Lois. I would love to see that version.

In The Longest Day, 55-year-old John Wayne played Lt. Col. Vandervoort and was 28 years older than the real Vandervoort.

I don’t think that any version of Frankenstein portrays Victor as anywhere near as young as the character is indicated to be in the book (He’s an undergraduate, and probably les than 20). Colin Clive was 31. Leon Vitale (probably the youngest Victor Frankenstein) was 29. Kenneth Branaugh was 34.
The equally-young Robert Walton is rarely portrayed, but in one version he’s played by 69-year-old Donald Sutherland (!)

Hopefully the latest reincarnation of Spiderman captures the spirit of youth by casting Tom Holland as the high schooler.
He was 20 during filming but he has a much more youthful look and sound than Tobey Maguire (27 then) and Andrew Garfield (29 then).

Pocohantas was about 12 years old when she met John Smith, so…

Severus Snape would have been more accurately played by an actor in his 30’s.

Sean Connery, then 69, might have found a more age-appropriate love interest in, say, Kathleen Turner, then 45.

Kathleen Turner would then put on the catsuit and writhe her way through the lasers in Entrapment.

Also, she ran around naked and apparently the adult male colonists were quite fond of her. An accurate Pocohatas would likely result in prison for both the people involved in making the film and the people who watched it.

Frodo Baggins was the equivalent of middle-aged in The Lord of the Rings book trilogy, not like the Jackson films where Elijah wood was 18-19 during filming. Not sure what difference that would make, but Peter Jackson did wonder why so many people complained about many of his changes (elves at Helm’s Deep, no Tom Bombadil, etc.) whereas no one ever said a word about the age difference.

Leonard Whiting was 23 when he played Victor in Frankenstein: The True Story.

We tend to think of Prince Albert as a stodgy, middle-aged prig, but even though he was pretty priggish from early on in life, he was only a boy of 20 when he married Victoria, a few months younger than she was. Yet I note that in television shows and movies that deal with their courtship and early married life, he’s played by men much older, usually in their 30s. Rupert Friend, at 29 in Young Victoria, seems to come closest to the correct age.

I thought he was about 50, which is barely into adulthood in Hobbit years…

If only Frodo was played by someone who looks and acts more mature than Elijah.

I’d go see that play. Come to think of it I actually have seen that play, but all the actors were middle school students so it doesn’t exactly have the same effect as what you’re suggesting.

Yeah, but the title is misleading…

It works out to about mid- to late-30’s in human years. 33 is the age of majority for hobbits.

Yea, and then they join the militia, and everyone knows it’s near-impossible to overcome a force of Hobbit.

Gone With the Wind, with a sixteen year old girl(at the beginning) as Scarlett. Vivien Leigh was 26 when she played that role.

It’s interesting that the actress that played Scarlett’s mother, Ellen O’Hara, was actually a little younger than what the lady would have been. Ellen, at the start of the book, was about thirty-two years old, having married the forty-one year old Gerald when she was fifteen. Barbara Neill, was twenty-nine when she played Ellen.

Jenna Coleman and Tom Hughes both look quite young in ITV’s recent series–at 29 she’s convincing in portraying the 18 year old Victoria, maybe because she’s small (her bio says 5’2" and I’ve read speculation that she may be just 5’1") and round-cheeked. Tom Hughes was 29 when he played a 20 year old Albert, also convincingly.

I remember arguments that people would have found Humbert far less sympathetic in the movie Lolita if Lolita had been cast at her actual age, instead of a 15-year old playing 11/12. (BTW, I had no idea that movie was that old–it looks more recent in clips I’ve seen.)

I think Smallville would feel very different if the actors actually looked like ninth graders when they started, but I’m not sure how to articulate it. What’s weird is how I didn’t notice until someone pointed it out–I’m just used to it.

I do remember one movie version of Romeo and Juliet that had an age appropriate Juliet that seemed a lot creepier. It’s the one where you very briefly see her nude onscreen.

I’ve always assumed that Jethro was in his mid- 20s, BTW. I figured everyone was just being nice in acting like he was just a boy. Similarly, I understood Jed as having letting Ellie Mae get away with “acting like a boy” for a long time, and so she was at least 18-19.

Or, if he wasn’t, I assumed that he was like me and some of my friends in the Ozarks who look a lot older than they actually are. I mean, I had my full beard in ninth grade and was at my full 6’2", which is apparently unusual. (One person apparently tried to become my friend in that grade because they thought I might be able to buy them cigarettes–that I looked old enough not to card.)

BigT, were you referring to the early 60s Lolita (Kubrick), or the 90s one with Jeremy Irons?

I think your comment is spot-on for the Kubrick version, and also (though less markedly) for the later version.
