Would a Catholic priest refuse a funeral due to suicide?

In the movie [Constantine](https://www.imdb.com/title/tt0360486/) , Rachel Weisz's character begs a Catholic priest to give her twin sister a funeral, but he refuses because she committed suicide. Is this an accurate depiction of Catholicism? I know expecting fair or accurate religious portrayals from the heathens that run Hollywood is probably expecting too much. Wondering how accurate that is?
