Katzenberg, in a telephone interview, described Biden as "energetic" and "effective," and suggested Republican attacks on his age will backfire.
"President Biden's age is, in fact, his superpower," Katzenberg said.
Some Democrats expect such attacks on Biden's age and family will increase in 2024.
Former Disney executive Katzenberg's opinion is likely to be reflected in Biden's campaign in the months to come.
Biden's campaign had four members on the payroll and spent a total of $1.1 million in the first three months since launch.
