Is it weird to be attracted to an actor that's over 20 year older than me?

I'm a 16 year old girl and I have crushes on several actors that are like 20 years older than I am, especially Christian Bale and Paul Bettany. It's not that I think that they're super y or anything, I just think their smile/laugh are really attractive and their voices sound really hot. Most girls my age have crushes on people like Zac Effron, but I think he looks too girly and pretty, and I usually prefer guys that look more mature. Is this weird?
