Get ready for a smorgasbord of new HBO documentaries over the next several months.  From a New York billionaire accused of murder (not once, but three times) to former Scientologists to Kurt Cobain and Frank Sinatra, nothing is off limits this year.

Keep reading to see what HBO Documentary Films has in store.

The Jinx: The Life and Deaths of Robert Durst is set to premiere Sunday, February 8, and run through March 15, and spotlights Robert Durst, the scion of New York's billionaire real estate family, who has been accused of three murders over the past 30 years, but never convicted. Brilliant, reclusive and the subject of relentless media scrutiny, Durst has never spoken publicly -- until now. Directed and produced by Andrew Jarecki and produced and shot by Marc Smerling (the Oscar nominees behind Capturing the Friedmans), the groundbreaking six-part documentary series tracks Durst's strange history against the backdrop of unimaginable wealth and privilege. The filmmakers' seven-year investigation and the extraordinary relationship that evolves between filmmaker and suspect ultimately reveal secrets that have baffled authorities for 30 years.

Going Clear, based on Pulitzer Prize-winner Lawrence Wright's book, airs March 16 and is directed by Oscar winner Alex Gibney (HBO's Mr. Dynamite: The Rise of James Brown and Taxi to the Dark Side). The film profiles eight former members of Scientology, exploring the psychological impact of blind faith and shining a light on how the controversial church attracts true believers.

Montage of Heck is scheduled for May 4 and is the first fully-authorized documentary about the iconic leader of Nirvana, taking the viewer on a raw and visceral journey through Kurt Cobain's life. The film provides no-holds-barred access to Cobain's archives, including his never-before-seen home movies, recordings, artwork, photography, journals, demos, personal archives and songbooks. Directed by Oscar nominee Brett Morgen (HBO's Crossfire Hurricane and The Kid Stays in the Picture) and executive produced by Cobain's daughter, Frances Bean Cobain, it features dozens of Nirvana songs and performances, as well as previously unheard Cobain originals.

Sinatra: All of Nothing At All will premiere later 2015, and is an intimate examination of the life, music and career of the legendary entertainer. Told in his own words from hours of archived interviews, along with commentary from those closest to him, the documentary weaves the music and images from Sinatra's life together with rarely seen footage of Sinatra's famous 1971 "Retirement Concert" in Los Angeles. Focusing on Sinatra's first 60 years, and drawing on comments from friends and family, as well as never-before-seen footage from home movies and concert performances, this unprecedented tribute to the beloved showman follows Sinatra's growth from roadhouse performer to global singing sensation.
