A futuristic rifle used in Star Trek, Superman's suit and Green Hornet's car are the top-billed items in a Hollywood auction next month, when fans and collectors will have a chance to own memorabilia from film sets and actor closets.

The one-of-a-kind Phaser laser rifle carried by actor William Shatner as Captain James T. Kirk in the second pilot for Star Trek from 1966 is expected to fetch between $50,000 and $70,000, Julien's Auctions said on Monday.

A black Imperial Crown car called "Black Beauty," belonging to The Green Hornet and used in the 2011 film starring Seth Rogen as the masked vigilante, is expected to fetch between $40,000 and $60,000. It was the only one to survive the production.

The rifle and car will be joining more than 800 lots of items at the Hollywood Legends auction spanning decades of Hollywood film history.

One hot collector item is a Superman outfit, complete with red cape and boots, worn by late actor Christopher Reeve in Superman IV. It is expected to fetch between $20,000 and $30,000.

Items belonging to Marilyn Monroe, including a cocktail dress and collections of photographs from films and model shoots, are also on the auction block.

Items will be on display from April 1 at a free public exhibition and the auction will take place online and at Julien's Auctions in Beverly Hills on April 5 and 6.
