Kelsey Grammer, star of the Frasier revival on Paramount+, has hinted at a potential crossover with the iconic British sitcom Only Fools and Horses. This crossover could reunite Nicholas Lyndhurst, who plays Professor Alan Cornwall in Frasier, with his former co-star Sir David Jason, known for his role as Derek 'Del Boy' Trotter. Grammer suggested that Jason could make a cameo, possibly by saying a famous line from the show, adding nostalgia for fans. Grammer praised Lyndhurst as an exceptional actor and expressed excitement about expanding his role in future episodes. Original cast member Wendie Malick has expressed reluctance to return due to her connection with the late John Mahoney, highlighting the emotional ties cast members have with the original show.
