Three sixty-something friends ( Robert De Niro, Morgan Freeman and Kevin Kline) take a break from their day-to-day lives to throw a bachelor party in Las Vegas for their last remaining single pal (Michael Douglas).

But Vegas has changed in the decades since the foursome last lapped the strip.

Hangovers and spinning rooms are on the cards for this legendary pack who can’t smoke, drink, eat salt or stay up past 9pm. Cocktails, pool parties, late night bars, roller-coasters and shot-lines see this bucks party kick on like its 1959.
