His father, Pyotr Evgenievich Fedorov (27 October 1959 - 10 March 1999), was a Soviet and Russian theater and film actor, art critic, television presenter (died of cancer at the age of thirty-nine).

In 1997, after receiving an incomplete secondary education, he entered the Moscow Theater Art Technical School (MTTU), after which he planned to enter the Stroganov Moscow State University of Arts and Industry, but after his father's death changed his decision and left the school after the second year of training.

After the third season, Pyotr left the project and began preparing for the shooting in the sci-fi film directed by Fyodor Bondarchuk Dark Planet (2008) based on the novel of the same name by Arkady and Boris Strugatsky.

In 2009, Pyotr appeared in one of his most significant projects at that time – Russia 88, a Russian pseudo-documentary film drama directed by Pavel Bardin about the youth subculture of the white power skinheads.

He played a supporting role in the 2014 film Territory by Aleksandr Melnik, a screen version of the novel of the same name by Oleg Kuvaev, which tells of the discovery of a gold-bearing deposit in the late 1950s of the 20th century.
