  reproducing motion picture film shall have, in  every  case  where  such
  persons or corporations copy, print, reprint, reproduce or in any manner
  prepare,  at  the request, with the consent or with the knowledge of the
  owner or his agent, a positive print or prints  from  a  motion  picture
  negative  film  for  the  owner  thereof,  or  for  a  lessee, licensee,
  mortgagee, conditional vendee or person in possession  thereof,  a  lien
  upon  such  positive  prints  and upon the negative film from which such
  positive print or prints were made,  printed,  reproduced  or  prepared,
  including the distribution and exhibition rights therein of all persons,
  firms  or  corporations  at  whose  request,  or with whose knowledge or
  consent such positive prints were copied, printed, reprinted, reproduced
  or prepared, and upon any and all other negative or positive  prints  or
  films  of  such owner, lessee, licensee, mortgagee or conditional vendee
  in their possession, including the distribution  and  exhibition  rights
  therein,  of  all such persons, firms and corporations aforesaid and may
  retain such negative and positive motion picture films at any time  they
  may  be  lawfully  in  their possession until the payment of any sum due
  from the owner of such negative or positive films or from any  licensee,
  lessee,  mortgagee  or  conditional  vendee  thereof  or from any person
  authorized to contract  for  such  work,  for  the  material  and  labor
  furnished,  including storage charges, insurance, cost of containers and
  money advanced in connection with the developing, printing,  reproducing
  and  preparing  of  such  motion  picture  negative  or  positive films.

  may  be  done  thereon  or  therefrom by such laboratory. No lien hereby
  granted shall be waived or impaired by the taking of any note  or  notes
  for  the moneys so due or for the work and labor performed and materials
  and moneys furnished.
