The individual who used an airsoft rifle to shut down the set of The Last of Us has committed a crime.

Forcing a set of the hit HBO series The Last of Us into lockdown by brandishing an imitation rifle from his apartment window should result in criminal convictions against an Olds man, a prosecutor argued Tuesday.

Crown lawyer Alyx Nanji said Reece Wadden’s conduct in the early morning hours of last June 1, should result in convictions for mischief and two firearms-related crimes.

He told provincial court Judge Brian Stevenson that Wadden’s actions struck fear into members of the cast and crew who had to take refuge for up to 90 minutes while police arrested the accused.

“Could he foresee people being scared as a result of pointing a gun out of his window? Absolutely, without a doubt,” Nanji said.

But defence counsel Peter Tesi argued his client had no criminal intent and was just using the scope of his airsoft rifle to get a better look at what was going on in the street below his second-floor apartment.

“All he was trying to do was get a clearer picture, a clearer view of what was taking place. He wasn’t pointing it at anyone,” Tesi said.

Costume assistant Steven Oben testified on Monday that he was sitting by a trailer when he noticed what appeared to be an individual holding a weapon out his window.

“I saw in a second-floor window what I thought to be some sort of gun,” he told Nanji.

“I turned to the person next to me and said ‘am I crazy, or is that a gun in the window?’ and he said ‘that’s a gun.’”

Oben said he alerted head of security Dustin Austin who attended and shone a flashlight at Wadden’s window before he retreated into the apartment.

Wadden, 19, denied pointing at the gun at anyone, and told court he only wanted to use his scope to see what was happening.

But Nanji argued his own admission was enough for Stevenson to find him guilty.

“You can’t look through the scope without pointing the gun,” he said.

The prosecutor also said Wadden’s actions amounted to mischief in that he shut down the production costing thousands of dollars in salary and other expenses.

Executive producer Rose Lam testified it was estimated the show paid US$54,000 in salary alone while staff took cover.

Lam said the hit show, which was shot in and around Calgary and other parts of Alberta, was filming a scene in which stars Pedro Pascal and Nico Parker are fleeing infected humans and a police car bursts into flames after colliding with their pickup.

Lam said they usually like to shoot at least two takes of such a scene, but because of the shutdown were only able to get one take that night.

Stevenson reserved his decision on the case. A date for his verdict will be set next week.
