You must be thinking-how do you create a believable Transformer that fits into the space of a fully functioning motorcycle?The answer is to get 6 custom built bikes from RetroSBK.Dreamworks actually contacted the owner Will Kenefick who has since worked ridiculous man hours to get these six bikes (the turnaround for one usually being 6 months), ready in time for filming.He estimates that 1273 hours were put in and that each bike cost $40,000, with $10,000 on paint alone (which added a further 1036 hours of work). Because the bikes are small it is expected that they will be showcased at the movie’s première.So that's how much is put into making Transformers movies!Can't wait for 2009!!
