London, Aug 24 (IANS) Hollywood actor Brad Pitt has raised his voice against the executives responsible for the Gulf of Mexico oil spill, saying they deserve the death penalty.

The 'Inglourious Basterds' star spoke out against those behind the oil rig explosion in April, which caused the worst environmental disaster in US history with millions of gallons of oil flooding into the sea, in a new documentary 'If God is Willing and Da Creek Don't Rise'.

'I was never for the death penalty before - I am willing to look at it again,' contactmusic.com quoted Pitt as saying.

The BP oil spill affected wildlife and the habitat of marine and coastal animals. It also caused loss of livelihood for many fishermen and other people who depend on the area for work.

Brad's comments are at the end of the documentary filmed by Spike Lee. An estimated 4.9 million barrels of oil leaked into the Gulf of Mexico during the 87-day spill.
