Let's start with Mila, who's credited with being a real-life wonder woman.
The 28-year-old actress was at her L.A. residence on Saturday when, according to TMZ, a 50-year-old man in her employ suffered a violent seizure and began choking, coughing up blood and vomiting.
Kunis responded immediately, dispatching a friend to call 911, while she reportedly rushed to the man's side, grabbed his head and turned it sideways so he wouldn't choke. Another person on the scene forced a wallet into his mouth to stop him from biting his tongue.
Paramedics soon arrived and rushed the man to the hospital. Mila offered to accompany him in the ambulance to the hospital but was told by first responders there was no need. The employee was said to have made a full recovery. (While authorities confirmed an emergency response to the home, E! News was unable to independently verify Mila's heroics.)
The incident capped a scary week for the Black Swan star, as the day before LAPD arrested a man for allegedly stalking her at her Beverly Hills gym.
As for Hoffman, the erstwhile Hero star is being heralded for saving the life of a jogger who collapsed after suffering a heart attack.
Hoffman was enjoying a morning stroll through London's Hyde Park when he witnessed 27-year-old Sam Dempster suddenly keel over, grab his chest and begin frothing at the mouth.
Jumping into action, the 74-year-old actor rushed to his aid, dialed 999 for paramedics and remained by his side until an emergency crew arrived, initiated CPR and successfully restarted the man's heart.
"My newfound favorite celebrity Dustin Hoffman," Dempster, who's recovering after undergoing a heart operation, wrote on his blog.
All in a day's work for the Marathon Man, who owns a $16 million mansion in nearby Kensington.
