Howard the Duck was a 1986 movie made by Lucasfilms. It starred a duck named Howard (of course) who lived in a universe where duck lives as man (insert dramatic thunderclap), but is brought to our universe by some sort of science fiction macguffin. It was based on the character of the same name from Marvel Comics who actually dates back to 1973. While the comic character still turns up from time to time, the movie was considered a horrendous, career poisoning flop.
One major issue with the movie (beyond the story, script, and all that jazz), is simply the duck suit effects. Not only is Howard not convincing or particularly emotive, he's unpleasant to look at. He is also incapable of letting loose with his quack-fu, a manner of martial arts that should easily take down the likes of even Chuck Norris. In this movie, there's no way he can unleash a proper fury.
But what about today?
Ignoring for a moment the obvious option of traditional animation (as pointed out by several critics at the time), we now have fairly convincing CGI and motion capture technology. If you'll recall Yoda in the Star Wars prequels, the technology does exist to make someone like Howard into a convincing fighting bad-ass. It also would allow him to be more expressive and natural in general.
Now, I'm not suggesting you could take the same script, toss in CGI Howard and call it a day. Hell no. I'm suggesting that the lack of limitations imposed on Howard by virtue of him not being some guy in a suit would give greater flexibility to what's done with him, and give the writer's more to work with. There could be cool action sequences, the comedic timing would be better... actually, they could use a similar script and it would be better. It wouldn't be good, but the basic addition of range to Howard would improve on the original.
It could still suck even with a new script and CGI, but this is ultimately my point: I believe there are movies out there that were crippled by the technological limitations of their time. The limitations affected both where they could go with the script and how scenes could be executed. Are there flops out there that, given modern technology, should possibly be given another chance? If so, is Howard among them?
