A film crew using a smoke machine while working in a canyon off State Route 52 prompted concerned commuters to call 911 to report a possible fire off the freeway.
There was, however, no fire, city public information officer Jose Ysea confirmed.
The film crew’s machine caused smoke to billow just before 7:10 a.m. off eastbound SR-52 at Genesee Avenue in University City.
The San Diego Fire-Rescue Department (SDFD) was initially called to the area to investigate a possible brush fire.
Once the film crew was discovered in the canyon – and the group’s smoke machine – the firefighter response was canceled.
No one was hurt.
