Honestly, the dude playing Kirk is 28, but he just doesn't look old enough. I am not sure if this is just because of the trend towards actors playing much younger roles in movies and TV or whether they just made him look young as fuck, but I'm a little disappointed.
One thing I do really like about this though is how they have updated the look of the bridge but how you just know it will look as equally dated and ridiculous to people in 30 years time as TOS does to us now.
Still looking forward to it though, I have good feelings about this movie.
