Let me make one thing clear.for the most part, the mentality of those who run the show in Hollywood frankly p*sses me right off in general and even more specifically in relation to its treatment of much loved, iconic characters from the pages of comic books. Why? Well let's take a typical Hollywood executive board meeting scenario to illustrate shall we..
Executive no.1 'Hey there's lots of dollars to be gleaned from superhero flicks these days.'
Executive no.2 'Good point, let's make one with haste then!  We'll do a lucky dip in a hat and pick out a superhero at random to base a film upon!' (The dip takes place and a famous superheroes name is pulled out)
Executive no.1 'Great! Now who can we get to play the part?'
Executive no.2 'Who's a big box office star at the moment?'
Executive no.1 '*name of big actor* is the in thing this week.'
Executive no.2 'But does he really suit the role? I mean he doesn't resemble the character whatsoever.'
Executive no.1 'Who cares?! He's a big name; We'll make the film with him in it anyway.'
Executive no.2 'You're quite right! And besides we'll fill the entire film so chock full of glitzy special effects to appease the moronic masses that no one will ever question it anyway!'
The above scenario clearly illustrates one of the reasons I generally loath most modern superhero movies. All style, no substance and simply pathetic casting of the iconic leads. Of course to be equitable, there are exceptions to the above rule; when Hollywood does get it right  take the casting of the original (and still easily the best!) Superman; Christopher Reeve and more recently Patrick Stewart and Sir Ian McKellen in the X-Men films.
But back to the general negative traits displayed by Hollywood today..wouldn't it be wonderful if our studio executives were to ALWAYS choose actors who actually suited the roles? Well in this less than ideal world, one filmmaker does just this believe it or not, by casting actors based upon their genuine resemblance to their comic book counterparts. His name is Sandy Collora. Sadly (but typically) Hollywood has not as of yet allowed Collora to direct a full length film but luckily for us, he has given us tantalizing glimpses of what the finished outcome would likely look like in the form of two (as of yet) famous super hero short features. One is the superb Batman:Dead End and the other is this mock trailer for an entirely fictitious film called Worlds Finest.
Well, let's not mince our words here  this is absolutely awesome stuff!
The casting of Mr. Universe winner and male model Michael O'Hearn, (who looked similarly awesome but was utterly wasted in the lackluster Barbarian) makes for the most perfect choice to play the iconic man of steel. In fact, in terms of physical resemblance, there has undoubtedly never been a closer approximation to the comic character.
Added to this Clark Bartram is back fresh from his splendid portrayal as the Dark Knight in Batman:Dead End; Again, yet another hugely judicious piece of casting!
What can I say?  If only this was indeed a real, full length film! Hollywood studio executives  take note! THIS is how it should be done!
As a final note, I am once again intrigued by the vastly split reactions this short film has evoked from fans. Tellingly, the most acerbic and vehemently adverse reactions against it clearly come once more (as similarly with Batman: Dead End) from a younger, less cinematically experienced audience; a fact betrayed by their somewhat grammatically primitive rants and liberal usage of base diction. Such an unfortunate state of closed mindedness is indeed a sad phenomenon albeit one that our aforementioned studio executives in Hollywood, will no doubt derive great satisfaction from. After all, these very same misguided individuals are in all probability the exact same sort of CGI addicted, popcorn stuffing imbeciles that revel in the majority of crap that Hollywood churns out by the deluge these days.

"Serum" starts out with credits that are quite reminiscent of the "Re-animator" movies, and it owes a lot to them. The story is very similar; a mad doctor develops a serum that he believes will alleviate pain, sickness and death, but he's apparently not a big believer in clinical trials and so winds up with a brain-eating zombie on his hands in the person of his nephew. The zombie even looks like one of those from "Re-animator," and in fact some of the make-up effects in "Serum" aren't bad. Unfortunately, the script is pretty slow and unbelievable in quite a few places, resulting in a soap opera feel for most of the first 3/4 of the movie. For some reason, the director feels compelled to tell us the time of day every few minutes by flashing it in big white letters across the screen. I can't see why this was important, other than being an attempt to provide viewers with a sense of time passing; sometimes, that wouldn't be present otherwise as the plot plods along.
There are a number of moments that just don't add up here. For instance, one victim is bludgeoned with a sledge hammer, but when we see the victim's head up close, there's no sign of that trauma. In another scene, a character runs down a fully lit hospital corridor (we can see the circles of light on the floor, in fact) with a flashlight in hand, looking for all the world like he's walking in the dark... but a moment later a second character walks down the same fully-lit corridor without one. These are just a couple of examples; moments of what look like directorial or editorial sloppiness crop up quite frequently throughout the movie.
"Serum" is better in some ways than much of what goes straight-to-video as independent horror lately. In terms of technical items  sound and photography, for example  it's got a more polished look than a lot of what lands on a DVD. On the other hand, there's still a good deal of wooden acting (particularly by one of the lead characters, the mad scientist himself!) and nonsensical moments that have nothing to do with suspension of disbelief and everything to do with writing and continuity. Maybe these are things that the people involved with making this film will eventually get more experience with, though. One of the problems with low-budget independent horror lately is that the filmmakers often set out to remake more popular movies that had bigger budgets, and that almost never works out. It didn't in the case of "Serum," anyhow.
