FCP 720 vs 1080 projection

If I'm eventually going to be screening FCP output in a theater (250 seats) will I be ok capturing at 720p DVCProHD or will I need better resolution for projection? Obviously my concern is how much storage I'll need for 1080 on a feature.

How will it be projected? What will be the playback device? I played my DVCPRO HD 720p24 ANDREW JACKSON show from hard drives via a Christie 2K projector onto a 20" screen (obviously smaller than a 250 seat theatre), but it looked great. Mixed Varicam and HVX-200.

That's about how we'd do it. Thanks for the info. Yes, 20' is smaller but I think the 720 will be fine for us. Hell, we used to screen DV so it's only up from there!
