Security is going to unprecedented lengths to keep the stars safe at Sunday's Academy Awards.
Hundreds of officers will be on hand to make sure nothing goes awry at the first Oscar show since the terrorist attacks in San Bernardino, California and Paris, which reportedly took the lives of at least 144 people.
In the past, beefed-up security measures at the Oscars included metal detectors, which everyone was required to pass through, LAPD SWAT snipers, bomb-sniffing dogs and undercover agents dressed in formalwear to blend in.
This year, there are expected to be overt and covert measures taken to make sure the show comes off without a hitch. Secret Service will also be on hand with the announcement that Vice President Joe Biden will be introducing Lady Gaga's performance at the show.
As officers prepare to keep the stars safe, some nominees were spotted returning to Los Angeles on Wednesday.
Best Actor nominee Matt Damon talked Oscar odds just moments after landing at LAX, telling photographers Sylvester Stallone has a "good shot" at winning the statuette in the Best Supporting category for his role in Creed.
