Along with the cast of Legends of Tomorrow, Oliver Queen and Barry Allen (Grant Gustin) will set off on a chase that jumps from Star City to Central City in surprising fashion.

"Most of the 'Flash' episode takes place in Star City, and most of the 'Arrow' episode takes place in Central City," Amell revealed. "We have a common villain, which was not the case last year, and just in general, we've done an excellent job of weaving not just two shows, but three shows together."

Are you ready for a massive DC mashup? Episode titles and air dates will be forthcoming.

The Flash airs Tuesdays at 8 p.m. ET on The CW and Arrow airs at 8 p.m. ET on Wednesdays.
