“The Flash” star Ezra Miller was catching looks at a lounge in Hawaii over the weekend, dancing wildly just weeks after their arrest at a nearby bar.

Eyewitnesses say Ezra was all over the place at the Hilo Axe lounge in Hilo, HI Friday night … their moves caught the attention of the crowd, with one witness calling it “comical.”

Ezra was dropping it low and trying to break dance for the patrons — shaking their long hair back and forth for the camera.

Ezra’s been running into trouble at Hawaiian bars lately … as we reported, EM was denied entry to a bar on Hilo last month.

Things apparently got heated after the actor was physically blocked from going inside … the police came to calm things down.

The “Fantastic Beasts” star was arrested a few weeks later for disorderly conduct and har*ment after an incident at another bar  … allegedly grabbing the mic from a woman performing karaoke and lunging at a guy playing darts.

We’ve reached out to Ezra’s team for comment … so far, no word back.
