http://jason.whitehorn.ws/2008/06/17/Friendly-404-Errors-In-ASPNET-MVC.aspx gives the following explanation:
Add a wildcard routing rule as your final rule:
routes.MapRoute("Error",
"{*url}",
new { controller = "Error", action = "Http404" });
Any request that doesn't match another rule gets routed to the Http404 action of the Error controller, which you also need to configure:
public ActionResult Http404(string url) {
Response.StatusCode = 404;
ViewData["url"] = url;
return View();
}

Just an FYI, The above linked post is returning a 404 (oh the irony). The new address is: jason.whitehorn.ws/2008/06/17/…
BC.
The only problem here is that so much matches the typical /{controller}/{action}/{id} route. To get around the problem, I explicitly defined all my routes and got rid of it.

Unfortunatelly the link doesn't work. Even jason.whitehorn.ws is not accessible :|

This is fine for situations where routes don't match, but doesn't help when an id is not valid for example...

@JasonWhitehorn 404 again
You can also override HandleUnknownAction within your controller in the cases where a request does match a controller, but doesn't match an action. The default implementation does raise a 404 error.

Good idea. Check out this solution which incorporates a
HandleUnknownAction override: stackoverflow.com/questions/619895/…throw new HttpException(404, "Resource Not Found");

With MVC 3 you can return HttpNotFound() to properly return a 404.
Like this:
public ActionResult Download(string fontName)
{
FontCache.InitalizeFonts();
fontName = HttpUtility.UrlDecode(fontName);
var font = FontCache.GetFontByName(fontName);
if (font == null)
return HttpNotFound();
return View(font);
}
