    WHERE theater_name='theater_name'");

    while($row = mysql_fetch_array($result))

This is the google maps code

 function initialize() {
        var latlng = new google.maps.LatLng(12.91869,77.594051);
        var myOptions = {

Use mysql_fetch_assoc() to get associative array from your database since you are getting only one result:

<?php
    mysql_select_db("theatdb", $con);
    $result = mysql_query("SELECT Lat,Lon FROM theaters WHERE theater_name='theater_name'");
    $row = mysql_fetch_assoc($result);
    echo $row['theater_name'];
?>

<script type="text/javascript">
function initialize() {
    var latlng = new google.maps.LatLng(<?php echo $row['Lat'];?>,<?php echo $row['Lon'];?>);
    var myOptions = {
      zoom: 12,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
}
</script>
