Rob,
It looks like you've already gotten the answer to your question. Like Keith says, the number varies slightly from source to source, but 172 is fairly close. Of course, that doesn't include his appearances in TV shows and other things, such as documentaries.
We'd also like to take this opportunity to welcome you to the Original John Wayne Message Board! As you can see, we are friendly, knowledgeable, and international. You are not alone, but have many fellow Canadian members here.
We look forward to getting to know you better in the days and weeks to come. Don't be a stranger :teeth_smile:!
Chester 
and the Mrs.
