The original cast included Ogie Alcasid, Michael V., Gelli de Belen, and theatre/voice actors Nonie Buencamino, Manny Castañeda, Earl Ignacio, Sheilou Bharwani, Mhalou Crisologo, Ana Abad Santos and Lorna Gay Long.
In 1997, however, Tropang Trumpo was reformatted again and introduced a new powerful ensemble led by the ever-loyal Smokey Manoloto, Sunshine Cruz and Keempee de Leon.
In early 1998, some key people in the production team led by Edgar Mortiz, Al Tantay and Dan Salamante left due to conflict with ABC executives.
The ABC management named Al Quinn and Ding Bolanos as replacements for Tantay and Mortiz, while surviving lead cast members Gelli de Belen, Carmina Villaroel and Candy Pangilinan headlined the reformatted show together with Caloy Alde, Raffy Rodriguez, Diego "Binoy" Salvador and Onemig Bondoc.
Among the new cast members joining the reformatted show were Anjanette Abayari, Rufa Mae Quinto, Lindsay Custodio, Daniel Pasia, Blakdyak and Jake Roxas.
