This paper demonstrates how media historians can gain valuable insight by using newspapers as well as fiction films as their primary source materials. It exhibits the value of considering press and cinema sources next to one another, through a case study of the representation of London's public transport network in popular newspapers and fiction films of interwar Britain. Through a close reading of relevant newspaper articles and films, it becomes evident that whilst both media paid heed to the sensational and potentially hazardous aspects of public transport, newspaper reports also sought to reassure readers which used transport every day. This indicates a more complicated relationship to the dangers of modernisation than an analysis of fiction films alone would suggest. Newspapers and films provide adjacent, complementary forms of representation. The press report on real-life events, but increased commercialisation of the press means that fictional storytelling devices are frequently used by reporters. Fiction films provide the inverse; its made-up stories need to be grounded in reality to permit audiences to connect with them. Considering both media alongside one another can create a new and richer understanding of social and cultural history.
