“Fist Fight” (*** out of four) was an often very funny comedy about the escalating feud between two teachers (Charlie Day, Ice Cube) which leads to an after-school fight. Hard to tell at first that this is a remake of 1987’s “3 O’Clock High” but it is, with teachers instead of students. Story is slim and script is contrived but it features enough laughs to make it worthwhile. Day is likeable and funny and Ice Cube is ferocious and hilarious in a perfectly cast role, and they play off and work well against one another.
