"Books are fun. Even the classics are fun or inspiring," said Plummer.
The Oscar-winning actor grew up in a family that valued, loved and shared the art of reading.
"Language is fascinating and rich, and it's as I say in the play, it's our heritage," said Plummer. "The kids should know that reading is really quite wonderful and fun. It isn't dull or dreary, so I hope that this show illustrates that."
Plummer pays tribute to a host of his favorite authors, from Shakespeare to Dylan Thomas to Lewis Carroll.
"'Alice in Wonderland' is really the first book that really affected me, because it's so full of imagination. It just started mind going," said Plummer. "That's probably one of the most original books ever written."
The 84-year-old actor also challenged himself by writing the piece as a one man show. He says "going solo" makes a willing audience all that more important.
"It's not like you're in a play with six or seven other people. The audience, in this case, is your partner," said Plummer. "I know enough now, after all these years, how to get them to listen and then how to stop and listen to them."
Plummer has been performing for more than 60 years. He firmly believes keeping one foot planted firmly in the theater helps him stay vibrant.
"It's terribly important, because this is where you build your craft. It reminds you of what you are supposed to be," said Plummer.
"A Word or Two" plays at the Ahmanson Theatre through Feb. 9.
