Speaking with ET backstage at the convention in Philadelphia, the Power Rangers star opened up about collaborating with Rachel Platten on the a capella cover of her popular song, and bringing together some of her favorite friends to be a part of the video.
"I've been to a few Hillary rallies and [I've been] hearing that song. I love Rachel Platten and she just said yeah, let's do it," Banks told ET's Nischelle Turner. "It's a really fun journey, and [it was great] to have it revealed tonight [after Bill Clinton's speech]. It's just been a really fun evening."
Banks, who directed and starred in Pitch Perfect 2, said that the song was ideal for an a capella cover because "there's harmony and strength in many, many voices. I just felt like that message would be carried [through] if we made that kind of video out of 'Fight Song.'"
Banks also addressed Michelle Obama's powerful speech from the first night of the DNC, where she reflected about raising her daughters in the White House, and managed to slam Donald Trump without ever uttering his name.
"That was shade of the highest order," Banks marveled. "She's so gracious and regal and amazing."
