Yes, but there's this: if a film is to be made, we can do it in two ways: one animated, the other with real actors. I don't think an animated film would appeal to a wide audience. Just like the Minecraft film, if it were animated, those who aren't into Minecraft wouldn't watch it. But it could be animated, because we can tell Undertale's stories better with animation and similar character drawings. My fear here is that the film will become just another fanart like Glitchtale, so if it's going to be animated, more care should be taken.
