He wasn't sure if he'd be asked back for the upcoming sequel after his small role in the 2014 smash hit.

But Benicio Del Toro clearly had an impact on Marvel Studios as he was spotted on the Guardians of the Galaxy Vol 2 set on Friday.

The 49-year-old actor sported a white wig and brows while heading to his trailer during breaks between filming.

The Academy Award-winning actor played Taneleer Tivan - aka The Collector - in the original sci-fi movie.

He wore a grey tee that tucked into his black trousers as suspenders hung low around his waist.

Originally, the actor was not sure if he would be asked to return for James Gunn's second volume.

Benicio confessed he would like to further develop his role as the white-haired eccentric in an interview last year with IGN.

'I would like to keep working on that character, though,' he admitted.

'It was kind of like a cameo. I would like to keep developing the character based on what’s written in the comic books.'

He added: 'I’d like to see some different sides. I had a blast working with James Gunn and the cast - but it’s not up to me.'

The James Gunn-directed film features an all-star lineup including Chris Pratt as the ripped Star-Lord character and Zoe Saldana as the green-faced Gamora.

Alongside the trio returns Dave Bautista's Drax, psychopathic racoon Rocket, and humanoid tree Groot, who are voiced by Bradley Cooper and Vin Diesel respectively.

The original was a surprise blockbuster in 2014, raking in just over $773 million worldwide, more than recouping its $170 million budget.

Guardians of the Galaxy Vol 2 is due in theaters May 5, 2017.
