With contributions from the likes of Leonardo DiCaprio and Martin Scorsese, HBO's upcoming Steven Spielberg documentary is more of a love-in then a tell-all but with his career documented from the get-go in the '70s, there's plenty to get excited about.

The documentary will premiere at the New York Film Festival on October 5th before its debut on HBO so the jury is still out on the 147-minute doc's content, but with J.J Abrams, Francis Ford Coppola, Liam Neeson, Cate Blanchett, Brian de Palma, and many more featuring, at least there'll be a lot to watch.

Here's the official synopsis:

Through exclusive interviews with actors, family, and the filmmaker himself, this unprecedented documentary pulls back the curtain on the remarkable career of Steven Spielberg. Featuring Leonardo DiCaprio, Martin Scorsese, Liam Neeson, and many more. 

And here's how New York Film Festival have billed it:

"Susan Lacy’s Spielberg traces the private, public, and artistic development of one of cinema’s true giants, from his early love of moviemaking as a kid growing up in all-American suburbia, through his sudden rise to superstardom with Jaws, to his establishment of a film-and-TV empire with DreamWorks and beyond. All along the way, Spielberg has approached every new film as if it were his first. Featuring interview with friends and contemporaries in the ‘New Hollywood’ (Francis Coppola, Brian de Palma, George Lucas, Martin Scorsese); key artistic collaborators (including Tom Hanks, John Williams, longtime DP Janusz Kaminski); and, the film’s most touching presences, Spielberg’s beloved sisters and parents, Arnold and Leah"

'Spielberg' airs on HBO on Saturday October 7th, and with any luck Sky Atlantic will have it ASAP.
