Several adaptions show Fezziwig's Christmas party as the setting for where Scrooge first met Belle, whom he fell in love with and became engaged to. Some adaptions such as Scrooge (1970) (where Fezziwig is played by Laurence Naismith), and the 2017 stage version even depict Belle (renamed as Isabel for the former adaptation) as being one of Fezziwig's daughters.
In the 1951 film Scrooge, Fezziwig is advised to bend with the times and sell out:
Jorkin: "Mr. Fezziwig, we're good friends besides good men of business. We're men of vision and progress. Why don't you sell out while the going's good? You'll never get a better offer. It's the age of the machine, and the factory, and the vested interests. We small traders are ancient history, Mr. Fezziwig."
Fezziwig: "It's not just for money alone that one spends a lifetime building up a business…. It's to preserve a way of life that one knew and loved. No, I can't see my way to selling out to the new vested interests, Mr. Jorkin. I'll have to be loyal to the old ways and die out with them if needs must."
Ultimately, Jorkin hires away Scrooge and buys out Fezziwig's business, moving it from private to shareholder ownership. As Fezziwig sadly watches, Scrooge notices him in the carriage, and seems to wade towards him as though to give explanations but, with an expression of guilt, walks away. As agent of shareholder interests, Jorkin and his managers Scrooge and Jacob Marley are constrained from diverging from the goals of profitability, making it more difficult to be a Fezziwig even if they were inclined to. Fezziwig's successor, Jorkin, demonstrates the weakness of self-interest when he announces to the board of directors that the company is insolvent after years of embezzling. Scrooge and Marley demonstrate their cunning self-interest by using the crisis to attain a controlling interest in the company. In Scrooge, these new managers replacing the Fezziwigs are predatory towards shareholders and employees alike, the product of a process and a mindset that Dickens felt was at odds with humanity.
Fezziwig appears in the 1983 animated featurette, Mickey's Christmas Carol, portrayed in a non-speaking role by Mr. Toad and the name spelled as "Fezzywig".
In the 1992 film The Muppet Christmas Carol, he is played by Fozzie Bear and called "Fozziwig". Unlike his book counterpart, Fozziwig is still alive and is given a gift by Scrooge following his redemption.
In the 1999 TV film A Christmas Carol, he is portrayed by Ian McNeice.
