No, not at all. My point is that even if the film had starred an old and frumpy actor, then would have still needed to apply a bunch of makeup. The character being in makeup is part of the character.
Spoilers for Digger
Tom Cruise is playing a character named "Curtis Markson" in the film. That character is in a satirical stage play where he plays "Digger Rockwell". The reveal that the film is actually a stage play is a surprise that occurs about 20 minutes into the film.
There are a number of hints in the first 20 minutes. For example the opening of the film has a "curtains rise" that in the moment feels like a stylistic choice. Another is an obviously robotic cat. Another is when we're seeing characters move about the house and enter the scene the building layout doesn't really make sense with characters playing with doorways. And finally the fact that Tom Cruise is heavily done up in makeup.
