The guard and prisoner bonded over their love of The Big Lebowski when Wood was sent to the prison for a nine-month tour in 2005

Wood wrote a letter of recommendation when Slahi petitioned the U.S. government for release in 2016 

Slahi was released from the prison six months later - after 14 years in custody

Wood visited during the Ramadan holiday, so the two shared break-fast meals and Wood bonded with Slahi's extended family over soccer games 

The former Army sergeant said he hopes to return to visit his friend again 

Slahi, a former Al Qaeda member, wrote a memoir of being tortured behind bars, and claims he was wrongly detained
