The final episode of 'Catastrophe' will pay tribute to the late Carrie Fisher.

The comedy series will come to an end after the end of the current fourth series and co-creator Sharon Horgan has promised there will be a special nod to the 'Star Wars' legend, who had a guest role as Mia Norris, the mother of Rob Norris (Rob Delaney) for the first three sasons.

Sharon told RadioTimes.com: "It's the last episode we're ever going to do, and I can tell you that it's a little bit of a tribute to Carrie Fisher.

"I can tell you that we really wanted to mess with everyone's heads. It's emotional, and it's a little bit longer than usual.

"All of Rob's family are there, and it's not in England. That's enough, right?"

Sharon and Rob had confirmed the show was coming to an end before the start of series four and she admitted they felt it was the right time to bow out while people were still enjoying the programme.

She said: "We've been doing it for a long time - from the start of it to now it's probably six years - doing a show that we absolutely love, and getting to a point where we thought, 'Well, what if we can't think of something that's original and funny anymore?'

"I would say writing episode four was maybe the hardest one in terms of coming up with stuff that felt original or new or like we had something new to say. So I think we just felt like, maybe, quit while we're ahead."

However, the pair haven't ruled out bringing back the show in the future.

Sharon added: "And also, you know, maybe down the line like in 10 years or whatever, it doesn't mean that it's dead and over for good forever. But it just means that's it for now."
