The funnyman lost his battle with pancreatic cancer in February (14) shortly before the cast reunited for the first time in 10 years to film a one-off skit for U.K. charity telethon Sport Relief.
Jim Sullivan, son of the show's late creator John Sullivan, has now revealed Lloyd-Pack was due to reprise his role as hapless roadsweeper Trigger in the reunion, but the script had to be re-written when it became clear he would not be well enough to perform.
Sullivan tells British magazine Radio Times, "We were all shocked and saddened at the news of Roger Lloyd-Pack's death. We had originally written Trigger into the sketch and Roger was supportive of the whole thing. We had heard that he had been unwell, but had no idea how serious it was. It wasn't until shortly before filming that we heard he was too poorly to perform, such was his eagerness to be involved - a true testament to his character."
Sullivan goes on to insist the reunion really is a one-off as the cast has no plans to film a full series, adding, "It's... good to be able to set the record straight about some of the rumours... that we're writing a new series etc. None of it is true. It really is just a one-off sketch... There was only ever one writer of Only Fools and Horses, and without him, there can be no more."
The reunion sketch will air as part of the Sport Relief telethon in the U.K. on Friday (21Mar14).
