Use mysql_fetch_assoc() and assign $row database values:

<?php
    $link = mysql_connect("localhost", "root", "root") or die (mysql_error());
    mysql_select_db("theaterdb", $link) or die(mysql_error());
    $strSQL = "SELECT address FROM theaters WHERE theater_name='" . mysql_real_escape_string($_POST['course']) . "'";
    $rs = mysql_query($strSQL);
    $row = mysql_fetch_assoc($rs);
    mysql_close();
?>

<script>
  var infoWindow = new google.maps.InfoWindow({
    position: latlng,
    content: '<b>Theater Address:</b><br> <?php echo $row['address']; ?>'
  });
</script>

For a side note, you can try to move your code to PDO as mysql_* functions are deprecated, check this nice tutorial.
