What are the Best and Worst Performances in Science Fiction and Fantasy?

SciFi Weekly columnist (and author) Michael Cassutt looks at what it takes to act in a science fiction film or series.

What are some you your best and worst choices for SF (or fantasy) acting?

For me there’s…

The Good: The entire cast of Firefly; Tom Cruise in Minority Report; Johnny Depp in Pirates of the Carribbean.

The Bad (too numerous to mention really, but off the top of my head): Just about anyone in the original Dune; Whoever played King Arthur in Excalibur; Hayden Whatsisname in Star Wars I, II and undoubtedly III (His acting is so course…like sand. OK, Lucas gets the raspberry for poor writing on that one, but still.)
