June Whitfield swears people "won't be disappointed" with the new episodes of Absolutely Fabulous.
The award-winning series, which aired from 1992 to 2005, marks its 20th anniversary with two special episodes this Christmas.
June, who plays Edina Monsoon's mother, said recording the episodes was like "going back to school" and that the studio audiences were responding really well.
"People are really looking forward to it and won't be disappointed," she said.
"The people [in the audience] were obviously all thinking, 'Oh my goodness, will it be as much fun as it was before?' and after the show they said, 'Yes, yes, it is'. They absolutely loved it.
"Jennifer and Joanna are terrific, Jane is hysterical and the minute the audience saw them or heard their voices, they were shrieking. It was a great atmosphere."
Without wanting to spoil the surprise, fans will rejoin the ensemble in the midst of a life-changing experience for one character.
In the second episode, Eddy sets her sights on changing the career of a certain 'big fish', and in the concluding episode (to be aired in the summer) Eddy and Patsy play their own very special role in the Olympics.
:: One-off episodes of Absolutely Fabulous are on BBC One on Christmas Day and New Year's Day.
