i went and saw hp3 on an imax (10 stories tall, not 6 tho) and i thought it was really cool! ive seen lotr 1 and spiderman on the imax and they were pretty cool, but i liked harry potter the best, it felt like u were right there and the WB sign felt like it was gonna hit u and i just thought it was amazing... its not like the movies MADE for imax but i definitely thought it was cool
