Paul Grant, an actor who appeared in the Star Wars and Harry Potter films, has died aged 56 after being found collapsed outside a train station.

Grant was found outside King’s Cross station in north London on Thursday afternoon.

He was pronounced dead at 3.49am on Monday but had been declared brain dead before that following his collapse. The cause of death has not been disclosed.

Grant, who played an Ewok in Return of the Jedi and a goblin in Harry Potter and the Philosopher’s Stone, appeared as one of the Goblin Corps in the cult 1986 classic Labyrinth alongside David Bowie and Jennifer Connelly.

The actor also served as the stunt double in Labyrinth for Hoggle, who was performed by Shari Weiser and voiced by Brian Henson.

His other film credits include Legend, the 1985 Tom Cruise film, and the 1988 film Willow.

His daughter, Sophie Jayne Grant, confirmed his death to Sky News.

She said: “I’m heartbroken … No girl deserves their dad to be taken away … He was so well known and loved [for his work]. He’s gone too soon.”

A London ambulance service spokesperson said: “We were called at 2.08pm on Thursday 16 March to reports of an incident at St Pancras Station, Euston Road.

“We sent an ambulance crew and a medic in a response car. We treated a man at the scene and took him to hospital as a priority.”

Grant is survived by his girlfriend Maria Dwyer, his two daughters and one son, as well as his stepchildren and grandchildren.

Dwyer paid tribute to the actor, saying: “Paul was the love of my life. The funniest man I know. He made my life complete. Life is never going to be the same without him.”

Grant’s stepdaughter Stacey has set up a Go Fund Me page to raise funds towards his funeral. “I’m starting this page as Paul sadly passed away yesterday and I would like to give him the best send off he would want,” she said.
