Leland "Pookey" Wigington, the president of Hart's production company, told NBC News on Tuesday that Hart "is doing fine after back surgery and is expected to have a full recovery very soon."

TMZ reports cops are investigating whether speed was a factor in the crash as a witness claims to have heard tires screeching, shortly followed by the sound of the car smashing through fencing. A spokesman for the California Highway Patrol was not immediately available for comment when contacted by Yahoo Entertainment. Black was behind the wheel of Hart's beloved vintage Plymouth Barracuda when it crashed about 10 feet off Mulholland Highway and into a ditch. TMZ obtained wreckage photos that showed the roof completely crushed by impact and the car destroyed.

Black was found pinned in the driver's seat under the roof. A female passenger, identified as Black’s fiancé Rebecca Broxterman, was also pinned. Black, who police say had not been drinking, was airlifted to UCLA Medical Center and his condition is unknown. Broxterman was unharmed. Hart left the scene after being picked up by his security, a witness told TMZ, and was taken to his nearby home. He was later treated for his injuries at a local hospital.

On Monday, Eniko Hart told TMZ her husband was "going to be just fine," saying he was "great" and "awake," but declined to comment further about his condition. The Jumanji: Welcome to the Jungle star has yet to issue a public statement about the incident. He bought himself the Barracuda in July as a 40th birthday present.

Prior to the crash, Hart posted a photo of himself "happy" at home.

Well-wishes for Hart have been pouring in on social media. Dwayne Johnson told his friend to "stay strong."
