our only perception of Indiana Jones is through Harrison Ford.
Not for the most inclusive of us.
There are novels, comics, and video games to which Harrison only contributed his likeness. Indy's actions, emotions, and personality are portrayed by writers and programmers. And although those traits are based on the movies, they are not derived from Harrison Ford himself, but from something Harrison Ford created.
To go a step further, there are 43 episodes / 22 movies depicting Indiana Jones in which Harrison's involvement is limited to less than 10 minutes of screen time. In fact, as Indiana Jones, Sean Patrick Flannery has five times as much screen time as Harrison Ford. But he is not Indiana Jones, either.
In my opinion, people who limit Indiana Jones to Harrison Ford are missing out on a lot.
