"Amazing Spider-Man 2" got off to swinging start, grossing an estimated $8.5 million from last night's late shows. That beats "Amazing Spider-Man"'s $7.5 million that it took from their early shows (but remember, those were on a Tuesday) yet it fell short of "Captain America: Winter Soldier"'s $10.2 that it nabbed from its Thursday night late shows earlier in the spring.
I was at the Hollywood Dome for their 8 pm show and the reaction was generally positive from those in attendance, a few of whom came dressed in Spidey garb. In answer to your next question, I left mine at home.
Most are predicting an opening in the CAWS range of $95 million. I have it a tad higher at $102 million. We'll see.
