Hypothetical Questions

[nalcomis]

Anyone know how to ask a hypothetical question in Japanese? Like, "What if we saw a movie?"

Or how about asking rhetorical questions?

Hypothetical questions, I find, are usually asked using the たら conditional.

一億円あったらどうしますか？(Ichioku-en attara, dou shimasu ka?)
If you had one hundred million yen, what would you do?

I'm a little confused about your example because it sounds like a suggestion...
You could say 映画を見たらどう（ですか）？ (Eiga o mitara dou [desu ka]?) - How about watching a movie? What do you say we watch a movie?
Is that the meaning you were going for?

Oh, sweet. I understand completely. English is a little more vague, I think, while Japanese specifically says "if we did this, would it be OK?" (example)

Thank you very much! ありがとうございます！
