I don't think so bud, I've watched the film a ton of times and every still from the film I've seen the buttons are just green plain old buttons. Not sure where you saw that, but it's news to me.
From the pic above, you can see he did have normal buttons at one point. But I've also seen pics with the quirky buttons. As others have said, the buttons on his vest must have changed - I didn't realize that.
I know i'm spending a fortune on this set, but i will feel good once i have it in my collection and i have of a true 1/6 grail figure, this thing will never loose it's value,so someone can't ever say that i have waisted my money...i could always sell this later in life if i wanted and get back what i spent to have it in the first place.
Just a word of warning - that's not something that's necessarily true, especially in this case. I've really followed the prices of these high end Batman-related figures, both official/mass produced and custom, for a few years now, and it's given me some insights. Let me explain.
Official figures, and especially Hot Toys figures, tend to increase in value over time (usually relatively rapidly). That tends to be the rule, rather than the exception. But custom figures and accessories don't follow that trend nearly as frequently - especially the more expensive ones. The demand for custom pieces is so much smaller - and also the supply is small enough that most who would demand it have since learned to accept the mass-produced items, so they don't contribute to demand. Both of these factors work against the item's price in the future.
So chances are, if you change your mind later, that you won't be able to make your money back (much less turn a profit). You'd probably be able to find a buyer, somewhere, but not at 100% of the price you sold it for - and again, this becomes more and more true as the price of the custom item increases.
There is also lots of anecdotal evidence for this. I think the BobbyC Joker sculpt is the latest example of this. One of the few owners of this very expensive item seems to be having a bit of trouble selling his, even at 15% cheaper than the price he paid for it.
I'm not saying that if you decide to sell it later, you won't be able to get all your money back. You might very well be able to - but please don't count on it happening, since the reliability of that is far less than that of normal figures.
I'm also not saying you should or should not get these items based on these facts. But I know that I often choose to buy a figure even if I'm not sure if I want it - because I know I'll probably be able to sell it at cost (if not for more) later, so it makes sense to err on the side of caution.
If this line of thinking is important to you when considering whether or not to make a purchase, and if the potential to recoup your investment is an important factor in your decision-making process, then it's important to realize that this logic doesn't hold up when discussing custom works like this.
Just make sure you know that you'll be happy in the long run, whatever you choose!
