You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: play_movie.m
    path of file: ./repos/CaImAn-MATLAB/utilities
    
    the code of the file until where you have to start completion: function play_movie(movs,labels,min_mov,max_mov)
    % play list (cell) of movies with labels, press key to stop playing
    % inputs:
    % movs: cell of movies
    % labels: cell of titles for movies
    % min_mov,max_mov: min and max of movie for setting clims on movies
    
    if ~iscell(movs)
        movs = {movs};

    
function play_movie(movs,labels,min_mov,max_mov)
    % play list (cell) of movies with labels, press key to stop playing
    % inputs:
    % movs: cell of movies
    % labels: cell of titles for movies
    % min_mov,max_mov: min and max of movie for setting clims on movies
    
    if ~iscell(movs)
        movs = {movs};
    end
    if ~exist('labels','var')
        labels = cell(size(movs));
    end
