Imagine waking up at 6 a.m. and realizing a scary-looking guy was in your home. The accused stalker is charged with breaking into Sandra Bullock's fortress mansion in Los Angeles.

Cops say Joshua Corbett somehow got over the barbed wire fence that surrounds Bullock's home and eluded the security cameras that are all around her property. It's believed he was on the grounds for at least an hour before America’s sweetheart realized he was there.

The quick-thinking Gravity star locked herself in a room and called police. Thankfully, her son, Louis, wasn't home at the time. He was spending the night at his nanny's house.

Corbett, a 39-year-old licensed pilot, now faces charges of stalking and burglary. A judge told him, "You must not come within 200 yards of Miss Bullock."

As if he wasn't scary enough, cops say they found a machine gun at his home. He has pled not guilty to all charges.
