Please help me to find a horror movie from the 80s or early 90s, I only saw one scene on TV in the mid-90s: a man in a dark jacket is standing in a big brightly lit office, lots of people around, he starts vomiting red and yellow-green substance (akin to blood and bile) covering the walls with stains, everyone is scared, then the man leans against the wall, his mouth begins to stretch extremely as if something is going to come out of it.
Maybe The Hidden (1987)?

Nice suggestion, thanks. But this isn’t it, there is no vomit scene. The movie looked similar in style. The man I’m talking about could be a little like Michael Nouri in The Hidden, at least the hair style.
