Zachary Quinto is nursing an injured hand after an unlikely incident with a water bottle cap.

The Star Trek actor took to Instagram on Monday morning (18Apr16) to post a photo of his left hand, wrapped in gauze, holding the cap of a San Pellegrino bottle.

"The offending object," Zachary wrote. "last night in london an adventure to be sure..."

He shared another photo of himself on a plane, reaching out with his injured hand to grasp a glass of champagne. He added the caption, "flying home. i can barely reach..."

Hours later, he was back in New York City and made no effort to hide his new bandage accessory while on the red carpet at the Tribeca Film Festival. Zachary happily posed for photos and signed autographs for fans with his non-injured hand before attending a screening of For The Love Of Spock, a new documentary about late Star Trek icon Leonard Nimoy.

Directed by Leonard's son Adam Nimoy, the film celebrates his late father's life and career, with a focus on his iconic character of Mr. Spock in the cult sci-fi series.

The film, which was funded by a successful Kickstarter campaign, is narrated by Zachary, who played Spock in J.J. Abrams' recent Star Trek movies.

Adam also interviewed Zachary's Star Trek co-stars Chris Pine, Zoe Saldana, Karl Urban, and Simon Pegg for the film, as well as all the surviving principal cast members from the original series, William Shatner, Nichelle Nichols, Walter Koenig, and George Takei.

Leonard Nimoy passed away in March, 2015, aged 83, after a battle with chronic obstructive pulmonary disease.
