Are there characters you could only imagine portrayed by specific actors…forever ?

Even if that actor is no longer with us ? Would seeing the character played by someone else be an adjustment ?

For me, Superman will always be
The late Christopher Reeve

The Black Panther will always be
The late Chadwick Boseman

Sherlock Holmes will always be
The late Jeremy Brett

And the X-Man Wolverine is
Hugh Jackman
