Liev Schreiber: Shirtless at the Water Park!

Liev Schreiber goes shirtless as he spends the day at a water park with his son Samuel on a warm Wednesday (June 1) in New York City.

The 43-year-old actor and his longtime love Naomi Watts are set to star together in the boxing drama The Bleeder.

The film is based on the true story of heavyweight boxer and womanizer Chuck Wepner who boxed 15 rounds with Muhammad Ali and inspired Sylvester Stallone to write Rocky, according to Variety.
