The actor revealed that director Christopher Nolan elected not to film scenes at the protests because he believed it would have sent the wrong message.
"The wisdom of Christopher Nolan and his incredible team was that, while it seemed like a good idea to give [the protesters] an opportunity for work, to give them money, it would send a terrible message," Modine told Indiewire.
He continued: At the end of the day, we're making a movie. What's happening down there is more important than that. To co-opt what's happening there and around the country… we didn't want to trivialise it.
"It was more important to respect what they're doing than to do anything that could potentially trivialise the political situation downtown."
Modine will play "a politician and a key villain" named Nixon in the follow-up to The Dark Knight.
The Dark Knight Rises arrives in US and UK cinemas on July 20, 2012.
