It's also important to note that:
* "Hilary and Michael" is not specific enough. There are many actors named Hilary and Michael. Are you referring to specific actors?
* Success is subjective. What one person considers a "down the toilet" career, another might see as a fulfilling journey.
* Careers are complex. An actor's success is influenced by a variety of factors beyond their talent, including luck, opportunities, and the changing landscape of the entertainment industry.
Instead of making judgments, it's more constructive to discuss specific actors and their work, analyze their career trajectories, and consider the reasons for their success or lack thereof.
