For me, he was James Bond whenever these movies came out. Roger wasn’t my favorite but he did star in several of the best movies in the franchise: Live and Let Die, The Man with the Golden Gun, The Spy Who Loved Me (despite being a lazy remake of You Only Live Twice), For Your Eyes Only (I grew to love this as I got older, it was a let down as a kid because I expected more gadgets) and Octopussy. Sadly, the only Roger Moore take I saw in a theater was his phoned-in finale, A View to a Kill.
Sean Connery was a tough act to follow too, as George Lazenby painfully learned, but Moore put his own touch on the character, namely the puns and his delivery of them.
I never saw his episodes of The Saint yet he was a funny presence in Cannonball Run and a surgically altered Clouseu in Curse of the Pink Panther. The Muppet Show did a humorous turn with him as well.
In the action department, I did enjoy him The Wild Geese which I recently re-watched last Summer since it was on Netflix. It was one of the few R-rated things my old man let me watch on HBO.
Thanks for the action Roger!
