What if Chris Hemsworth was not the one to be featured as the eponymous God of Thunder in "Thor," "The Avengers," and "Thor: The Dark World"? Could you imagine the movie without him?

There's something not quite right about the idea, mainly because at this point in Marvel movie momentum, Chris Hemsworth is Thor as much as Tom Hiddleston is his formidable foe/rival sibling Loki, Yahoo Movies reported.

But as Marvel and Hiddleston fans very well know, there was a time during the casting of the original "Thor" when Hiddleston attempted wielding the mighty hammer, Mjolnir.

Now, Yahoo Movies has the first glimpse of the British actor's audition tape for the role of Thor from the special features of the upcoming "Thor: The Dark World" DVD/Blu-ray.

"Even with those brief clips of Hiddleston-as-Thor, you can tell by his particular brand of cinematic intensity that his Norse God would have been decidedly different, even with his packed-on muscle and long blond wig," Yahoo Movies reported.

As executive producer Craig Kyle says in the video, "He did a tremendous job, but he wasn't Thor."

"Every English-speaking actor over 6 foot was being seen for the part," Hiddleston told The Guardian about his audition process. "I got down to the final few, which also included Chris's younger brother Liam Hemsworth ["The Hunger Games"], Alexander Skarsgård ["True Blood"], and Charlie Hunnam ["Pacific Rim,""Sons of Anarchy"]."

As we see in the clip above, the toned torso was done to pack on 20 pounds of muscle by lifting lots of weights and eating lots of protein roughly six weeks before the screen test.

Although that screen test didn't land him Thor, it landed him in "Thor," when director Kenneth Branagh - who had worked with Hiddleston on stage and TV - later sat him down and asked him to play Loki instead, Yahoo Movies reported.

In another Blu-ray bonus, there is behind-the-scenes footage of the scene in "The Dark World" where Loki disguises himself as Captain America, and Hiddleston got to wear the red-white-and-blue costume himself, according to Yahoo Movies.

Hiddleston told MTV that he shot the scene with Hemsworth first, and then "he showed Chris [Evans] my performance on tape, and he went and did an impression of me doing an impression of him."

Hiddleston said he will not be appearing in the upcoming sequel "The Avengers: Age of Ultron."

"Thor: The Dark World" will be available on Digital HD on Feb. 2, and Blu-ray/DVD on Feb. 25, Yahoo Movies reported.
