Toys (1992)

Eccentric toymaker Kenneth Zevo (Donald O'Connor) last wish is that his brother, Leland (Sir Michael Gambon), takes over the running of the business. Leland is out of touch with toymaking and reality too. The business should really have been given to his nephew, Leslie (Robin Williams), who was much more like Kenneth. When Leland starts making weapons instead of toys, Leslie decides to take action.
