Most film archives in the UK seem to offer online databases and information about accessing film. The presentation is generally dry, not particlarly visually engaging. I have mainly added ones that represent the more interesting looking websites, offering addtional features. This is the full list: http://filmarchives.org.uk/archives.html.) Some universities have specialist film collections, not necessarily promoted beyond the university.
Yorkshire Film Archive is based at York St John University, but has a completely separate identity. It has an online catalogue, YFA Online, which is fully searchable and includes some clips. It offers a list of useful key words, and you can also search by title, description, context and/or year. Browse allows you to search by theme, location or decade. Each title has quite detailed background information. Curated collections are organised by theme and provide a bit more background. There is also a 'guest curator feature.
The website also tells us that YFA offers research facilities, broadcasting footage, community access and copies of films for schools.
YFA is introducing some new features to promote interest and engagement - Memory Bank, Family Tree, Video Postcards and Yorkshire Calendar, though these do not seem to be available yet.

This website promotes France's film museum/archive/cinema. Its home page reflects its remit - which includes a museum, library and archive, as well as film screenings and events. It has an online database for researchers, but also does special features on the collections in the museum and archive: Zoom on an object, as well as 'virtual exhibitions'.
Scottish Screen Archive: a searchable database of Scottish film. It's based at the National Library of Scotland, and looks quite 'dry' and basic; but it has a good education and community access section: Scotland on Screen: http://scotlandonscreen.org.uk/. It also has a 'your films' page where you can make your own collection.
View over 200 hours of film for free from the East Anglian Film Archive.
East Anglia Film Archive website is essentially a database of films from the region, many of them viewable online. It is a university based collection, with the university link clear within the branding. It appears to be targeted at specialist audiences, although there is a themed 'highlights' section which allows some browsing. And there is a neat widget for browsing further on the 'Browsing' page.
It also contains papers and some artefacts which are available to view at the library.
Home to over 3.5 million items of historical significance, the National Media Museum has 8 floors of FREE galleries and 3 cinemas including the UK’s first IMAX.
As well as promoting museum visits, a film programme, an education programme, inviting people to 'get involved', and the online shop, this site showcases the extensive collections of the museum.
The collections are searchable online, and are divided into five categories: photography, cinematography, television, new media, and collection resources. Each category is then further sub-divided. This makes it easy to browse to see what is there; each item is supported by a brief description. A side menu allows for easy jumping between categories. Each item is accompanied by up to 6 links to other similar items.
The left sidebar also contains links to additional features of the site: 'Object of the month', 'On this day' (choose a date and see photos in the collection associated with it), Meet the team (information about and photographs of the team at work), Resources (information sheets, and a guide to the history of photography), research (information about visiting the musuem for research purposes); Donate and object (for people with objects that could be acquisitioned); Shop; and FAQ.
The right sidebar contains featured items, including an addition 'curator's choice'.
