promises to be "refreshing" but a new teaser trailer suggests it's also familiar.
The film reunites devious duo Eddie Monsoon and Patsy Stone on the back of a boat in the French Riviera, clinking cocktails as handsome men lounge nearby.
In the style of an advertisement, the voiceover begins: "straight up on the rocks and always with a twist."
"When you must have the best, be sure to choose something cool, something refreshing, something absolutely fabulous."
Jennifer Saunders and Joanna Lumley resume their roles as the heavy drinking, chain smoking best friends, who first charmed BBC viewers on a TV series of the same name in 1992. The initial run came to an end in 1995 and resumed again between 2001 and 2004.
In their latest adventure Eddie and Patsy flee to France without a dollar after causing a "major incident" at a London fashion party.
Surrounded by media hype they attempt to escape paparazzi and reinvent themselves.
Julia Sawalha will return to play Eddie's daughter Saffron, wile stars June Whitfield and Jane Horrocks also make an appearance.
The script, written by Saunders, will be directed by Mandie Fletcher.
