Daniel Radcliffe, girlfriend Erin Darke attend 'Weird' premiere at TIFF

You could be enchanted by the romantic date night picture of Daniel Radcliffe and Erin Darke.

On September 8 at the Toronto International Film Festival, where they were present for the world premiere of his new film Weird

The Al Yankovic Story, the Harry Potter actor, 33, and the Good Girls Revolt actress, 37

 made a rare red carpet appearance together. For the occasion, Darke wore a vivid blue 

dress with gentle waves and a crimson lip, while Radcliffe—who in the movie

plays "Weird Al" Yankovic—wore a striking pattern shirt under a navy suit.

Even though they haven't shared many red carpet moments together

 the couple has been together for a considerable amount of time—roughly 10 years.
