If they do it well, then yes. The odds of that happening (based off other video game movies) is pretty low so if they announced it I wouldn't get my hopes up for it.
I wouldn't mind watching a Movie Adaption of the Elder Scrolls books though. I've never gotten around to reading them and I generally don't mind Move adaptions of books.
Not sure if youre being curious or argumentive, but I'll gladly answer your question.
I really think it's common sense. While the TES lore is wonderfully rich, I just can't see it being pulled of in a way to appease to us die hard Elder Scrolls fans. What is TES about? Player's choice. Why would a movie be good for a game that promotes player's personal decisions? A movie is the complete opposite of that, and rather contradictory when you think about it.
I'm curious, but it's a point I'm willing to contend. I don't think we enjoy the in-game books (snippets though they may be) any less for not involving player choice. I imagine the ES novels that have been published would be reasonable comparison, but I have no idea whether or not they're successes. I haven't read them because if I did choose to indulge in non-gaming TES experience, I would want it to be based on stories that have already taken place, rather than original ones.
And though TES is about player choice, that doesn't stop die hard fans from enjoying lengthy "Lets Play" series' in which someone else is making all the choices, or indeed the fan fiction we have here. Quite a lot of it is more than two hours of material.
That's also true. But there's still a huge difference between the two. Let's Play's show off actual gameplay, glitches, grinding skills, etc. It's also still a game with a very different atmoshpehere. A movie, on the other hand, is simply watching a protagonist naturally get involved with a well organized, thought out plot.
Considering all of the stories that have come out of this site alone, it would clearly be difficult to chose one and fit it into even a three hour movie. The point of RPG's like TES is choice. A movie would show one choice, and it would probably show the most basic choice. Dragonborn who defeats Alduin. Boring. The audience would clearly be gamers, but we've seen that story. We've played that story. I wouldn't pay money to watch someone take a journey that I already took (especially since mine had a personal meaning). It would be a cash grab. So it could be done. And it would probably make money. But it would be a meaningless production.
I think that the Main quest in Skyrim could be made into a very thematic, epic, and fulfilling movie experience, but I don't think any studio would be willing to take the risk. It would probably need to be made as a trilogy just to encompass the climactic dragon battles, and that's with trimming a lot of fat from the story. If the world of TES was given the proper respect and had enough money and talent devoted to creating the movie I would buy a ticket in a heart beat.
However, I think if this movie were actually made it would be more like Dungeons & Dragons the Movie and less like The Hobbitt.
I think an Elder Scrolls movie wouldn't work out because first of all they need a character to choose, second of all there are too many choices. For example what if they did one on the civil war in skyrim would the character be a stormcloak or an imperial, would the protagonist be the dovahkiin or just a soldier, and for example they did the movie and the Stormcloaks win then all the Imperial fans would get really pissed and vice versa.
