    class read
    {
     
    	public static void main(String[]args)
    	{
          populateFilmVector();
     }
     
     
          static void populateFilmVector(){
         	String movie;
         	  Vector filmList = new Vector();
           try
           {
    	     File data       = new File("input.txt");
    	     FileReader fr = new FileReader(data);
    	     BufferedReader in = new BufferedReader(fr);
     
    	     movie = in.readLine();//read first line
    		 while(movie!=null)
    		 {
    			System.out.println(movie);
     
    			StringTokenizer tokens = new StringTokenizer(movie,",");
    			String title = tokens.nextToken();
    			String lead = tokens.nextToken();
                String length = tokens.nextToken();
    			String rating = tokens.nextToken();
    			String id = tokens.nextToken();

    the tockenizer isnt working
    Can you expand on that? How is it not working? What is it doing which it shouldn't? What isn't it doing which it should?

    You are printing out the line before using the String tokenizer on it, and then you are not doing anything with the parts that you get from the tokenizer.
