Olivia Jackson, who also worked on Star Wars: Episode VII - The Force Awakens, collided with a metal camera arm as she was filming a high-speed motorbike chase sequence in Johannesburg, South Africa on 5 September (15).

She suffered serious head injuries and a punctured lung, and remains in hospital fighting for her life.

Jovovich has now opened up about the accident in an emotional post on Facebook.com, revealing the whole crew is reeling from the tragedy.

She writes, "A terrible accident rocked our set on Saturday the 5th of September. My incredibly talented stunt double, Olivia Jackson, collided with a camera crane while performing a motorcycle stunt and it put her in the hospital with severe, multiple injuries. The cast and crew of Resident Evil: The Final Chapter have been totally devastated and are waiting with bated breath for news on her recovery - we now understand she is stable and being carefully monitored by very experienced South African doctors.

"I wasn't personally there to witness it, but from the reports I got, it was awful. None of us have experienced anything like this in our careers making action films and hope we never do again... It's a miracle that she survived."

Jovovich admits she did not know Jackson well but urges fans to pray for her recovery.

She adds, "I really looked up to her... It's a testament to Olivia's strength that she managed to survive... All of us here have been praying every single day for her and her family and sending our thoughts out hoping some of the positive energy reaches her, because she truly needs it... I would really appreciate it if you would take a moment out of your busy days ahead and pray for Olivia's full recovery too. She needs all the help she can get right now and every bit of the good energy we can send."
