Willis Family - Adam Willis

Adam Willis, played by Ian Williams, made his first appearance on 9 August 1990. Williams was invited to play the role of Adam shortly after he appeared in Bony, another Grundy production. Williams said the part appealed to him as it was flexible and Adam's humour kept him "fired up." Williams explained that he felt similar to his character as they both loved their families, but he was not impressed with Adam's naivety.

Adam is the eldest child of Doug (Terence Donovan) and Pam Willis (Sue Jones). When his parents and his younger sister Cody (Amelia Frid) decide to move to a smaller house in Ramsay Street, Adam opts to move with them as living on his own will be expensive as he is a medical student. The family move into Number 28 and Adam soon takes a job working for as a chauffeur for Helen Daniels's (Anne Haddy) limousine company Home James.

Adam soon falls for Caroline Alessi (Gillian Blakeney) and but she is involved with Jim Robinson (Alan Dale). Adam competes with Jim to win Caroline's affections which culminates in Adam injuring Jim during basketball practice, which fails to impress Caroline. After Jim and Caroline break up, Caroline realises she is attracted to Adam and they begin dating. However, Adam's struggle with expenses in his student lifestyle leave him feeling inferior; and as a result he and Caroline split but remain good friends.

After struggling at university, Adam decides he wants to give up medicine and drops out to join Doug on his building site. Doug, however isn't convinced and engineers a plan to make Adam's time on the site miserable so he will return to medicine. The plan is successful and Adam returns to university to pursue his degree, much to Pam's delight.

Adam later falls for Gemma Ramsay (Beth Buchanan). Gemma is reluctant to commit to him after a failed relationship with Glen Donnelly (Richard Huggett), but realises she has strong feelings for him and they become a couple. Several months into the relationship, Gemma receives a job offer in Newcastle at an animal sanctuary and she leaves. Adam follows her a month later when he transfers to a local university. Adam completes his studies and becomes a doctor. He and Gemma become engaged.

The BBC said Adam's most notable moment was "Chauffeuring a Lassiter’s client while wearing a toga."
