To all you wannabe movie makers out there don`t worry about plagerism because you can only be sued if you tear the top sheet containing the screenplay credits off and insert your new top sheet saying you`re the author of the screenplay . That`s the literal and legal meaning of plagerism , trust me I`ve been to film school and I know what I`m talking about and this knowledge must come as a relief to the producers of CHRISTMAS RUSH which is identical in plot to the original DIE HARD movie and when I say identical I do mean identical in every way even down to the bad guys , some of whom are German - I did say identical didn`t I ? - taking the hero cop`s wife hostage . Did I mention this film`s identical to DIE HARD ?
