Don't be disappointed if a favorite actor at a live performance is unwilling to make himself or herself available after the show. Even actors who are excellent performers are often painfully shy in real life. Famous actors, of course, are very unlikely to make themselves available at all.
One particularly exciting variety of movie theater is the IMAX version. IMAX theaters are often available in large venues, and in most metropolitan areas you can usually find a few. They show special huge-format films you'll see nowhere else.
Have you even considered using a theater for a business or trade show presentation? The theater is already equipped to handle a large audience, and in almost every case you'll have access to high quality sound, lighting, and multimedia systems.
