Anybody who's seen Melies' "A Trip to the Moon" should certainly watch this. It not only surpasses the run time of the earlier film, (resulting in a 20 minute production which was amazing for its time), it is visually astounding and fantastic. Even though Melies had already indulged in multi-scene spectacles by this time, this was without a doubt the "Intolerance" of its day. Visual effects, nice color, beautiful sets...wow.
Many people have been calling this a sequel to "A Trip to the Moon" and I can see why they're saying that, because it is yet again a sci-fi topic. Instead of the moon, however, the scientists here go to the sun. There's tons of build-up too. First, they have to build the means of transportation (a train). Then, they go on this huge journey through the Swiss landscape. Then, their car gets busted and they have to spend days in the hospital. Obviously, Melies was more or less padding it out with all this build-up, but with all the action and detail put into each scene, there is plenty to see.
Melies obviously had an imagination. Not only had anybody ever gone to the moon by 1902, ANY sort of space travel was unheard of. Thus, even now we realize how utterly impossible it is to go to the sun (through the mouth, no less). But Melies was all about creating the impossible. This movie is such a visual treat that even people today could be entertained.
Also, it can be noted a supplemental section to this was made, where Crazyloff manages to recover the equipment lost in the sun by using a gigantic magnet to pull it all back to earth. It is unknown whether this section has survived, as John Frazer claims to have once inspected a print, while Malthete lists the short as lost.
