Gibson’s credibility its probative value was low, and thus inadmissible, because insurance may be purchased for many reasons none of which necessarily relate to plaintiff’s knowledge or lack of knowledge of a usage of trade in the film industry. Accordingly, we find that the evidence that negative film insurance was available and that plaintiff actually had such coverage was properly excluded.
Next, defendant argues that the jury’s finding that the parties did not agree to limit defendant’s liability for the defective or negligent manufacture of film to replacement is not supported by any evidence and was contrary to the evidence of custom presented by Messrs. Drexler, Smith, Gradus, and Mason. Again, we disagree. Based on our review of the evidence11 we find that the jury’s verdict was not contrary to the weight of the evidence, was not seriously erroneous, and was not influenced by partiality or prejudice. Further, we find that there was no miscarriage of justice in the verdict as given by the jury. See Lind v. Schenley Industrie, Inc., 278 F. 2d 79 (8 Cir. 1960); Barrett v. Robinson et al, 65 F.R.D. 652 (E.D.Pa.1975). We, therefore, find that defendant is not entitled to a new trial on the grounds that the verdict is against the weight of the evidence.
Finally, defendant argues that the testimony of Donald Davidson, plaintiff’s damage expert, was improperly admitted and should have been stricken and that plaintiff’s damage evidence was, as a matter of law, inadequate to sustain a verdict in excess of $25,000. Again, we disagree. Davidson, as an expert rendering an opinion, testified that had “Childhood II” been released earlier, it would have grossed at least one million dollars. He based his opinion on the factors which determine the commercial success of a film — timing, advertising, and quality, and on a comparison of the films “Childhood II” and “Together.” His testimony of the factors which determine the commercial success of a film is admissible as testimony by a witness, qualified as an expert, which “will assist the trier of fact to understand the evidence or to determine a fact in issue.” Fed.R.Evid. 702. His testimony comparing the films “Childhood II” and “Together” and estimating the prospective profits of “Childhood II” is admissible as the testimony of a qualified expert in the film industry fully familiar with both the films “Childhood II” and “Together”.12 Thus, we find

In Western Show Company, Inc. v. Mix, 315 Pa. 139, 141, 173 A. 183, 184 (1934) the Supreme Court of Pennsylvania permitted the testimony of expert witnesses familiar with the damage question in issue to calculate the damages defendant caused. The court stated: Following the decision in Western Show Co., Inc. v. Mix the court in Guady v. Seaman, 188 Pa.Super. 475, 478, 149 A.2d 523 (1959) affirmed the trial court’s decision to permit plaintiff to prove profit loss by the expert testimony of a well qualified accountant familiar with plaintiff’s business. The Seaman court cited Mix for the proposition that expert testimony is admissible to prove damages which plaintiff has suffered by reason of defendant’s breach of his contract where the witnesses are qualified and there is no reasonably safe basis for measuring the loss. Recently, in Nemitz v. Bell Telephone Co. of PA, 225 Pa.Super. 202, 207-208, 310 A.2d 376, 379 (1973) the court, citing Williston on Contracts, Revised Edition, Vol. 5, Section 1346, p. 3781 stated that prospective profits may be proven by evidence of profits made by others in a similar business where the facts are not greatly different and that Citing Silver v. Television City, Inc., 207 Pa.Super. 150, 158, 215 A.2d 335 (1965) the court held Interestingly, the dispute in Silver concerned the testimony of the plaintiff, a person experienced in the entertainment field. He was permitted to testify as to the dollar value of a novel product which he claimed defendant had improperly used. Also see, Riley v. General Mills, Inc., 226 F.Supp. 780 (E.D.Pa.1964) ; Sablosky v. Paramount Film Distributing Corporation, 137 F.Supp. 929 (E.D.Pa.1955).
