Filming has been paused for Anne Hathaway's "The Witches" movie after a stagehand was stabbed with a knife in the neck by another crew member.

It all went down on the Warner Bros. Studios in Leavesden, Hertfordshire on Wednesday and the lot went into full lockdown mode, this according to DailyMail.

Cops were called and an ambulance took the injured stagehand to a nearby hospital. The attacker, who worked alongside the victim, has been arrested.

"Police were called at around 12.35pm today (Wednesday, June 19) to reports of an incident at Warner Brothers Studios in Leavesden," a spokesperson for the Hertfordshire police tells DailyMail. "One man sustained a neck injury and was taken to hospital by ambulance."

"A second man was arrested on suspicion of wounding with intent to do grievous bodily harm and is currently in police custody," they added. "It is believed the men are known to each other. Enquiries are continuing at this time to establish the circumstances around what happened."

According to the site, a brawl broke out between the two on the set with about 100 crew members around them. Bystanders rushed to help aid their wounded co-worker and news of the violent brawl quickly spread throughout the iconic lot.

The weapon is believed to be a Stanley knife.

The 1990 remake also features Octavia Spencer and Chris Rock. It's unclear if any of the stars were onset when the stabbing occurred.

Octavia Spencer was in London with the crew over the weekend celebrating the PAs and AD staff for the movie. Sitting at dinner, the group looked happy and friendly with one another.

Warner Bros. has denied to comment as this is an ongoing police investigation.
