It will release in May, and will reportedly feature the inside look at the life of Ledger as told by those in his inner circle. 

Ledger's stories will be the third subject to be tackled in the channel's "I Am" docu-series. Earlier, Bruce Lee and "Saturday Night Live" star Chris Farley were taken as subjects for the first and second subject.

Ledger died at the age of 28 on January 22, 2008 from an accidental mixture of prescription drugs. 

He is mainly known for his famous role of supervillain Joker in The Dark Knight for which he received the Best Supporting Actor trophy at the 81st Academy Awards posthumously.
