Michael Fassbender as Steve Jobs in First Trailer for Biopic

— -- Aaron Sorkin's "Steve Jobs" has had a rocky road, but in the first trailer to be released, Michael Fassbender looks the part and has this latest biopic heading for critical acclaim ahead of its October release.

Fassbender stepped in after "Steve Jobs" lost its original leads, Leonardo DiCaprio and Christian Bale, and now the Oscar nominee makes his first appearance in the 1-minute clip as the late Apple founder.

The first look opens with someone, presumably Jobs, comparing the two biggest events of the 20th century the Allies winning WWII and "this" -- which is probably a big Apple announcement.

“You can’t write code. You are not an engineer. What do you do?” you hear from Seth Rogen’s Steve Wozniak shortly after.

“The musicians play the instruments. I play the orchestra … I sat in a garage and invented the future," you hear what sounds like Jobs again.

Later on in the clip, we hear another voice, "No one sees the world the same way you do."

Then, it closes with Fassbender in Jobs' classic turtleneck. Check it out:
